  • how to insert multiple characters into a string in C [closed]

    - by John Li
    I wish to insert some characters into a string in C: Example: char string[20] = "20120910T090000"; I want to make it something like "2012-09-10-T-0900-00" My code so far: void append(char subject[],char insert[], int pos) { char buf[100]; strncpy(buf, subject, pos); int len = strlen(buf); strcpy(buf+len, insert); len += strlen(insert); strcpy(buf+len, subject+pos); strcpy(subject, buf); } When I call this the first time I get: 2012-0910T090000 However when I call it a second time I get: 2012-0910T090000-10T090000 Any help is appreciated

  • Concat wchar_t Unicode strings in C?

    - by Doori Bar
    I'm a beginner, I play with FindFirstFileW() of the winapi - C. The unicoded path is: " \\?\c:\Français\", and I would like to concat "*" to this path of type wchar_t (then I will use it as an arg for FindFirstFileW()). I made two test cases of mine, the first is ansi_string() which seem to work fine, the second is unicode_string() - which I don't quite understand how should I concat the additional "*" char to the unicoded path. I write the strings to a file, because I'm not able to print Unicoded characters to stdout. Note: my goal is to learn, which means I'll appreciate guidance and references to the appropriate resources regards my scenario, I'm very much a beginner and this is my first attempt with Unicode. Thanks, Doori Bar #include <stdio.h> #include <stdlib.h> #include <wchar.h> #include <string.h> #include <errno.h> void *error_malloc(int size); void ansi_string(char **str1, char **str2); void unicode_string(wchar_t **wstr1, wchar_t **wstr2); void unicode_string(wchar_t **wstr1, wchar_t **wstr2) { /* assign wstr1 with the path: \\?\c:\Français\ */ *wstr1 = error_malloc((wcslen(L"\\\\?\\c:\\Français\\")+1) *sizeof(**wstr1)); wcscpy(*wstr1,L"\\\\?\\c:\\Français\\"); /* concat wstr1+"*" , assign wstr2 with: \\?\c:\Français\* */ *wstr2 = error_malloc((wcslen(*wstr1) + 1 + 1) * sizeof(**wstr1)); /* swprintf(*wstr2,"%ls*",*wstr1); */ /* how should I concat wstr1+"*"? */ wcscpy(*wstr2,L"\\\\?\\c:\\Français\\"); } void ansi_string(char **str1, char **str2) { /* assign str1 with the path: c:\English\ */ *str1 = error_malloc(strlen("c:\\English\\") + 1); strcpy(*str1,"c:\\English\\"); /* concat str1+"*" , assign str2 with: c:\English\* */ *str2 = error_malloc(strlen(*str1) + 1 + 1); sprintf(*str2,"%s*",*str1); } void *error_malloc(int size) { void *ptr; int errornumber; if ((ptr = malloc(size)) == NULL) { errornumber = errno; fprintf(stderr,"Error: malloc(): %d; Error Message: %s;\n", errornumber,strerror(errornumber)); exit(1); } return ptr; } int main(void) { FILE *outfile; char *str1; char *str2; wchar_t *wstr1; wchar_t *wstr2; if ((outfile = fopen("out.bin","w")) == NULL) { printf("Error: fopen failed."); return 1; } ansi_string(&str1,&str2); fwrite(str2, sizeof(*str2), strlen(str2), outfile); printf("strlen: %d\n",strlen(str2)); printf("sizeof: %d\n",sizeof(*str2)); free(str1); free(str2); unicode_string(&wstr1,&wstr2); fwrite(wstr2, sizeof(*wstr2), wcslen(wstr2), outfile); printf("wcslen: %d\n",wcslen(wstr2)); printf("sizeof: %d\n",sizeof(*wstr2)); free(wstr1); free(wstr2); fclose(outfile); return 0; }

  • multiple valgrind errors: Conditional jump or move depends on uninitialised value(s)

  • Custom string class (C++)

    - by Sanctus2099
    Hey guys. I'm trying to write my own C++ String class for educational and need purposes. The first thing is that I don't know that much about operators and that's why I want to learn them. I started writing my class but when I run it it blocks the program but does not do any crash. Take a look at the following code please before reading further: class CString { private: char* cstr; public: CString(); CString(char* str); CString(CString& str); ~CString(); operator char*(); operator const char*(); CString operator+(const CString& q)const; CString operator=(const CString& q); }; First of all I'm not so sure I declared everything right. I tried googleing about it but all the tutorials about overloading explain the basic ideea which is very simple but lack to explain how and when each thing is called. For instance in my = operator the program calls CString(CString& str); but I have no ideea why. I have also attached the cpp file below: CString::CString() { cstr=0; } CString::CString(char *str) { cstr=new char[strlen(str)]; strcpy(cstr,str); } CString::CString(CString& q) { if(this==&q) return; cstr = new char[strlen(q.cstr)+1]; strcpy(cstr,q.cstr); } CString::~CString() { if(cstr) delete[] cstr; } CString::operator char*() { return cstr; } CString::operator const char* () { return cstr; } CString CString::operator +(const CString &q) const { CString s; s.cstr = new char[strlen(cstr)+strlen(q.cstr)+1]; strcpy(s.cstr,cstr); strcat(s.cstr,q.cstr); return s; } CString CString::operator =(const CString &q) { if(this!=&q) { if(cstr) delete[] cstr; cstr = new char[strlen(q.cstr)+1]; strcpy(cstr,q.cstr); } return *this; } For testing I used a code just as simple as this CString a = CString("Hello") + CString(" World"); printf(a); I tried debugging it but at a point I get lost. First it calls the constructor 2 times for "hello" and for " world". Then it get's in the + operator which is fine. Then it calls the constructor for the empty string. After that it get's into "CString(CString& str)" and now I'm lost. Why is this happening? After this I noticed my string containing "Hello World" is in the destructor (a few times in a row). Again I'm very puzzeled. After converting again from char* to Cstring and back and forth it stops. It never get's into the = operator but neither does it go further. printf(a) is never reached. I use VisualStudio 2010 for this but it's basically just standard c++ code and thus I don't think it should make that much of a difference

  • Can't seem to get C TCP Server-Client Communications Right

    - by Zeesponge
    Ok i need some serious help here. I have to make a TCP Server Client. When the Client connects to server using a three stage handshake. AFterwards... while the Client is running in the terminal, the user enters linux shell commands like xinput list, ls -1, ect... something that uses standard output. The server accepts the commands and uses system() (in a fork() in an infinite loop) to run the commands and the standard output is redirected to the client, where the client prints out each line. Afterward the server sends a completion signal of "\377\n". In which the client goes back to the command prompt asking for a new command and closes its connection and exit()'s when inputting "quit". I know that you have to dup2() both the STDOUT_FILENO and STDERR_FILENO to the clients file descriptor {dup2(client_FD, STDOUT_FILENO).

  • Strings in Objective-C++

    - by John Smith
    I just switched my code from Objective-C to Objective-C++. Everything goes swimmingly except for two lines. NSString * text1=[[NSString stringWithFormat:@"%.2f",ymax] UTF8String]; This line complains that error: cannot convert 'const char*' to 'NSString*' in initialization The second error related to the first is from the line: CGContextShowTextAtPoint(context, 2, 8, text1, strlen(text1)); It complains that error: cannot convert 'NSString*' to 'const char*' for argument '1' to 'size_t strlen(const char*)' Is there something I missed in the differences between ObjC and ObjC++?

  • ZF: How can I modify the error message for the required / notempty validator in the ini file

    - by heininger
    I'ld like to configure my forms using config with an ini file. I need individualized error messages like the following one: suche.elements.methode.options.validators.strlen.options.messages.stringLengthTooLong = "Der Suchbegriff '%value%' ist zu lang!" This works well for strlen and regex, but how do I set it up for "required" elements? I tried stuff like suche.elements.methode.options.validators.notempty.options.messages.isEmpty = "Der Suchbegriff darf nicht leer sein!" but this throws exceptions.

  • operator+ overload returning object causing memory leaks, C++

    - by lampshade
    The problem i think is with returing an object when i overload the + operator. I tried returning a reference to the object, but doing so does not fix the memory leak. I can comment out the two statements: dObj = dObj + dObj2; and cObj = cObj + cObj2; to free the program of memory leaks. Somehow, the problem is with returning an object after overloading the + operator. #include <iostream> #include <vld.h> using namespace std; class Animal { public : Animal() {}; virtual void eat() = 0 {}; virtual void walk() = 0 {}; }; class Dog : public Animal { public : Dog(const char * name, const char * gender, int age); Dog() : name(NULL), gender(NULL), age(0) {}; virtual ~Dog(); Dog operator+(const Dog &dObj); private : char * name; char * gender; int age; }; class MyClass { public : MyClass() : action(NULL) {}; void setInstance(Animal &newInstance); void doSomething(); private : Animal * action; }; Dog::Dog(const char * name, const char * gender, int age) : // allocating here, for data passed in ctor name(new char[strlen(name)+1]), gender(new char[strlen(gender)+1]), age(age) { if (name) { size_t length = strlen(name) +1; strcpy_s(this->name, length, name); } else name = NULL; if (gender) { size_t length = strlen(gender) +1; strcpy_s(this->gender, length, gender); } else gender = NULL; if (age) { this->age = age; } } Dog::~Dog() { delete name; delete gender; age = 0; } Dog Dog::operator+(const Dog &dObj) { Dog d; d.age = age + dObj.age; return d; } void MyClass::setInstance(Animal &newInstance) { action = &newInstance; } void MyClass::doSomething() { action->walk(); action->eat(); } int main() { MyClass mObj; Dog dObj("Scruffy", "Male", 4); // passing data into ctor Dog dObj2("Scooby", "Male", 6); mObj.setInstance(dObj); // set the instance specific to the object. mObj.doSomething(); // something happens based on which object is passed in dObj = dObj + dObj2; // invoke the operator+ return 0; }

  • (PHP) Validation, Security and Speed - Does my app have these?

    - by Devner
    Hi all, I am currently working on a building community website in PHP. This contains forms that a user can fill right from registration to lot of other functionality. I am not an Object-oriented guy, so I am using functions most of the time to handle my application. I know I have to learn OOPS, but currently need to develop this website and get it running soon. Anyway, here's a sample of what I let my app. do: Consider a page (register.php) that has a form where a user has 3 fields to fill up, say: First Name, Last Name and Email. Upon submission of this form, I want to validate the form and show the corresponding errors to the users: <form id="form1" name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <label for="name">Name:</label> <input type="text" name="name" id="name" /><br /> <label for="lname">Last Name:</label> <input type="text" name="lname" id="lname" /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /> <input type="submit" name="submit" id="submit" value="Submit" /> </form> This form will POST the info to the same page. So here's the code that will process the POST'ed info: <?php require("functions.php"); if( isset($_POST['submit']) ) { $errors = fn_register(); if( count($errors) ) { //Show error messages } else { //Send welcome mail to the user or do database stuff... } } ?> <?php //functions.php page: function sql_quote( $value ) { if( get_magic_quotes_gpc() ) { $value = stripslashes( $value ); } else { $value = addslashes( $value ); } if( function_exists( "mysql_real_escape_string" ) ) { $value = mysql_real_escape_string( $value ); } return $value; } function clean($str) { $str = strip_tags($str, '<br>,<br />'); $str = trim($str); $str = sql_quote($str); return $str; } foreach ($_POST as &$value) { if (!is_array($value)) { $value = clean($value); } else { clean($value); } } foreach ($_GET as &$value) { if (!is_array($value)) { $value = clean($value); } else { clean($value); } } function validate_name( $fld, $min, $max, $rule, $label ) { if( $rule == 'required' ) { if ( trim($fld) == '' ) { $str = "$label: Cannot be left blank."; return $str; } } if ( isset($fld) && trim($fld) != '' ) { if ( isset($fld) && $fld != '' && !preg_match("/^[a-zA-Z\ ]+$/", $fld)) { $str = "$label: Invalid characters used! Only Lowercase, Uppercase alphabets and Spaces are allowed"; } else if ( strlen($fld) < $min or strlen($fld) > $max ) { $curr_char = strlen($fld); $str = "$label: Must be atleast $min character &amp; less than $max char. Entered characters: $curr_char"; } else { $str = 0; } } else { $str = 0; } return $str; } function validate_email( $fld, $min, $max, $rule, $label ) { if( $rule == 'required' ) { if ( trim($fld) == '' ) { $str = "$label: Cannot be left blank."; return $str; } } if ( isset($fld) && trim($fld) != '' ) { if ( !eregi('^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.([a-zA-Z]{2,4})$', $fld) ) { $str = "$label: Invalid format. Please check."; } else if ( strlen($fld) < $min or strlen($fld) > $max ) { $curr_char = strlen($fld); $str = "$label: Must be atleast $min character &amp; less than $max char. Entered characters: $curr_char"; } else { $str = 0; } } else { $str = 0; } return $str; } function val_rules( $str, $val_type, $rule='required' ){ switch ($val_type) { case 'name': $val = validate_name( $str, 3, 20, $rule, 'First Name'); break; case 'lname': $val = validate_name( $str, 10, 20, $rule, 'Last Name'); break; case 'email': $val = validate_email( $str, 10, 60, $rule, 'Email'); break; } return $val; } function fn_register() { $errors = array(); $val_name = val_rules( $_POST['name'], 'name' ); $val_lname = val_rules( $_POST['lname'], 'lname', 'optional' ); $val_email = val_rules( $_POST['email'], 'email' ); if ( $val_name != '0' ) { $errors['name'] = $val_name; } if ( $val_lname != '0' ) { $errors['lname'] = $val_lname; } if ( $val_email != '0' ) { $errors['email'] = $val_email; } return $errors; } //END of functions.php page ?> OK, now it might look like there's a lot, but lemme break it down target wise: 1. I wanted the foreach ($_POST as &$value) and foreach ($_GET as &$value) loops to loop through the received info from the user submission and strip/remove all malicious input. I am calling a function called clean on the input first to achieve the objective as stated above. This function will process each of the input, whether individual field values or even arrays and allow only tags and remove everything else. The rest of it is obvious. Once this happens, the new/cleaned values will be processed by the fn_register() function and based on the values returned after the validation, we get the corresponding errors or NULL values (as applicable). So here's my questions: 1. This pretty much makes me feel secure as I am forcing the user to correct malicious data and won't process the final data unless the errors are corrected. Am I correct? Does the method that I follow guarantee the speed (as I am using lots of functions and their corresponding calls)? The fields of a form differ and the minimum number of fields I may have at any given point of time in any form may be 3 and can go upto as high as 100 (or even more, I am not sure as the website is still being developed). Will having 100's of fields and their validation in the above way, reduce the speed of application (say upto half a million users are accessing the website at the same time?). What can I do to improve the speed and reduce function calls (if possible)? 3, Can I do something to improve the current ways of validation? I am holding off object oriented approach and using FILTERS in PHP for the later. So please, I request you all to suggest me way to improve/tweak the current ways and suggest me if the script is vulnerable or safe enough to be used in a Live production environment. If not, what I can do to be able to use it live? Thank you all in advance.

  • Text Obfuscation using base64_encode()

    - by user271619
    I'm playing around with encrypt/decrypt coding in php. Interesting stuff! However, I'm coming across some issues involving what text gets encrypted into. Here's 2 functions that encrypt and decrypt a string. It uses an Encryption Key, which I set as something obscure. I actually got this from a php book. I modified it slightly, but not to change it's main goal. I created a small example below that anyone can test. But, I notice that some characters show up as the "encrypted" string. Characters like "=" and "+". Sometimes I pass this encrypted string via the url. Which may not quite make it to my receiving scripts. I'm guessing the browser does something to the string if certain characters are seen. I'm really only guessing. is there another function I can use to ensure the browser doesn't touch the string? or does anyone know enough php bas64_encode() to disallow certain characters from being used? I'm really not going to expect the latter as a possibility. But, I'm sure there's a work-around. enjoy the code, whomever needs it! define('ENCRYPTION_KEY', "sjjx6a"); function encrypt($string) { $result = ''; for($i=0; $i<strlen($string); $i++) { $char = substr($string, $i, 1); $keychar = substr(ENCRYPTION_KEY, ($i % strlen(ENCRYPTION_KEY))-1, 1); $char = chr(ord($char)+ord($keychar)); $result.=$char; } return base64_encode($result)."/".rand(); } function decrypt($string){ $exploded = explode("/",$string); $string = $exploded[0]; $result = ''; $string = base64_decode($string); for($i=0; $i<strlen($string); $i++) { $char = substr($string, $i, 1); $keychar = substr(ENCRYPTION_KEY, ($i % strlen(ENCRYPTION_KEY))-1, 1); $char = chr(ord($char)-ord($keychar)); $result.=$char; } return $result; } echo $encrypted = encrypt("reaplussign.jpg"); echo "<br>"; echo decrypt($encrypted);

  • C++ segmentation error when first parameter is null in comparison operator overload

    - by user1774515
    I am writing a class called Word, that handles a c string and overloads the <, , <=, = operators. word.h: friend bool operator<(const Word &a, const Word &b); word.cc: bool operator<(const Word &a, const Word &b) { if(a == NULL && b == NULL) return false; if(a == NULL) return true; if(b == NULL) return false; return a.wd < b.wd; //wd is a valid c string } main: char* temp = NULL; //EDIT: i was mistaken, temp is a char pointer Word a("blah"); //a.wd = [b,l,a,h] cout << (temp<a); i get a segmentation error before the first line of the operator< method after the last line in the main. I can correct the problem by writing cout << (a>temp); where the operator> is similarly defined and i get no errors. but my assignment requires (temp < a) to work so this is where i ask for help. EDIT: i made a mistake the first time and i said temp was of type Word, but it is actually of type char*. so i assume that the compiler converts temp to a Word using one of my constructors. i dont know which one it would use and why this would work since the first parameter is not Word. here is the constructor i think is being used to make the Word using temp: Word::Word(char* c, char* delimeters=NULL) { char *temporary = "\0"; if(c == NULL) c = temporary; check(stoppers!=NULL, "(Word(char*,char*))NULL pointer"); //exits the program if the expression is false if(strlen(c) == 0) size = DEFAULT_SIZE; //10 else size = strlen(c) + 1 + DEFAULT_SIZE; wd = new char[size]; check(wd!=NULL, "Word(char*,char*))heap overflow"); delimiters = new char[strlen(stoppers) + 1]; //EDIT: changed to [] check(delimiters!=NULL,"Word(char*,char*))heap overflow"); strcpy(wd,c); strcpy(delimiters,stoppers); count = strlen(wd); } wd is of type char* thanks for looking at this big question and trying to help. let me know if you need more code to look at

  • Is it alright to call len() in a loop's conditional statement?

    - by DormoTheNord
    In C, it is considered bad practice to call strlen like this: for ( i = 0; strlen ( str ) != foo; i++ ) { // stuff } The reason, of course, is that it is inefficient since it "counts" the characters in a string multiple times. However, in Python, I see code like this quite often: for i in range ( 0, len ( list ) ): # stuff Is this bad practice? Should I store the result of len() in a variable and use that?

  • PHP script keeps doing mmap/munmap

    - by Aurélien Momow
    Hello, My PHP script contains a loop, which does nothing much more than echoing and dereferencing pointers (like in $tab[$othertab[$i]]- stuff). It was working great until yesterday, when this script starting being VERY slow (like 50 times slower than before). After using strace, i figured out that 90% of the time, the script does mmap/munmap. Here is a random portion of the strace log : mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0152b000 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac014ea000 Here is the result of the strace -c command : % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 82.77 0.004092 0 13542 mmap 9.69 0.000479 0 3642 write 7.54 0.000373 0 13541 munmap 0.00 0.000000 0 100 read 0.00 0.000000 0 88 poll 0.00 0.000000 0 25 4 access ------ ----------- ----------- --------- --------- ---------------- 100.00 0.004944 30938 4 total Here is the php script : function affAnnonce($tabAnnonces, $isDoublon = 0) { GLOBAL $db, $base, $tabDomaine, $doublon, $traduction, $tab_contrat, $tab_emploi, $tab_categ, $tab_metier, $tab_region, $tab_departement, $tab_secteur, $tab_experience, $calc_all, $tabLangues, $tabLanguesNiveau, $tabNoAffAnnonce, $tabHisto; foreach($tabAnnonces AS $tmp) { if (in_array($tmp['id'], $tabNoAffAnnonce) === true) { continue; } $value->host = "../"; foreach($tabDomaine AS $domaine => $valeur) { if ($domaine == $tmp['domaine']) { $value->host = $valeur->host; break; } } // Ordre // secteur;metier;contrat;emploi;region;langues;domaine $tabPushModif = array(); if ($tmp['push_preview'] != '') { $tabPushModif = explode(';', $tmp['push_preview']); $tabPushModif['secteur'] = $tabPushModif[0]; $tabPushModif['metier'] = $tabPushModif[1]; $tabPushModif['contrat'] = $tabPushModif[2]; $tabPushModif['id_emploi'] = $tabPushModif[3]; $tabPushModif['regions'] = $tabPushModif[4]; $tabPushModif['langues'] = $tabPushModif[5]; $tabPushModif['domaine'] = $tabPushModif[6]; } $infoSoc = get_nom_societe($tmp['id_societe']); $number = ($tmp['nb_preview_push'] != '' ? $tmp['nb_preview_push'] : '&nbsp;'); $secteurs = explode ("/", $tmp[secteur]); $sector = ""; $count_sect = count($secteurs); for ($k = 0; $k < $count_sect; $k++) { if ($secteurs[$k] != '') { $sector .= $tab_secteur[$secteurs[$k]].'/'; } } $tmp['poste'] = apresinsertion($tmp['poste']); $tmp['metier'] = $tab_metier[$tmp['metier']]; $tmp['region'] = $tab_region[$tmp['region']]; $tmp['departement'] = $tab_departement[$tmp['departement']]; $tmp['secteur'] = $sector; $tmp['id_contrat'] = $tmp['contrat']; $tmp['contrat'] = $tab_contrat[$tmp['contrat']]; $tmp['emploi'] = $tab_emploi[$tmp['id_emploi']]; $tmp['categorie'] = $tab_categ[$tmp['categorie']]; echo '<tr id="'.($isDoublon ?

  • PHP Encrypt/Decrypt with TripleDes, PKCS7, and ECB

    - by Brandon Green
    I've got my encryption function working properly however I cannot figure out how to get the decrypt function to give proper output. Here is my encrypt function: function Encrypt($data, $secret) { //Generate a key from a hash $key = md5(utf8_encode($secret), true); //Take first 8 bytes of $key and append them to the end of $key. $key .= substr($key, 0, 8); //Pad for PKCS7 $blockSize = mcrypt_get_block_size('tripledes', 'ecb'); $len = strlen($data); $pad = $blockSize - ($len % $blockSize); $data .= str_repeat(chr($pad), $pad); //Encrypt data $encData = mcrypt_encrypt('tripledes', $key, $data, 'ecb'); return base64_encode($encData); } Here is my decrypt function: function Decrypt($data, $secret) { $text = base64_decode($data); $data = mcrypt_decrypt('tripledes', $secret, $text, 'ecb'); $block = mcrypt_get_block_size('tripledes', 'ecb'); $pad = ord($data[($len = strlen($data)) - 1]); return substr($data, 0, strlen($data) - $pad); } Right now I am using a key of test and I'm trying to encrypt 1234567. I get the base64 output from encryption I'm looking for, but when I go to decrypt I get a blank response. I'm not very well versed in encryption/decryption so any help is much appreciated!!

  • Problem with writing a hexadecimal string

    - by quilby
    Here is my code /* gcc -c -Wall -g main.c gcc -g -lm -o main main.o */ #include <stdlib.h> #include <stdio.h> #include <string.h> void stringToHex(const char* string, char* hex) { int i = 0; for(i = 0; i < strlen(string)/2; i++) { printf("s%x", string[2*i]); //for debugging sprintf(&hex[i], "%x", string[2*i]); printf("h%x\n", hex[i]); //for debugging } } void writeHex(char* hex, int length, FILE* file, long position) { fseek(file, position, SEEK_SET); fwrite(hex, sizeof(char), length, file); } int main(int argc, char** argv) { FILE* pic = fopen("hi.bmp", "w+b"); const char* string = "f2"; char hex[strlen(string)/2]; stringToHex(string, hex); writeHex(hex, strlen(string)/2, pic, 0); fclose(pic); return 0; } I want it to save the hexadecimal number 0xf2 to a file (later I will have to write bigger/longer numbers though). The program prints out - s66h36 And when I use hexedit to view the file I see the number '36' in it. Why is my code not working? Thanks!

  • Can someone explain me this code ?

    - by VaioIsBorn
    #include <stdio.h> #include <unistd.h> #include <string.h> int good(int addr) { printf("Address of hmm: %p\n", addr); } int hmm() { printf("Win.\n"); execl("/bin/sh", "sh", NULL); } extern char **environ; int main(int argc, char **argv) { int i, limit; for(i = 0; environ[i] != NULL; i++) memset(environ[i], 0x00, strlen(environ[i])); int (*fptr)(int) = good; char buf[32]; if(strlen(argv[1]) <= 40) limit = strlen(argv[1]); for(i = 0; i <= limit; i++) { buf[i] = argv[1][i]; if(i < 36) buf[i] = 0x41; } int (*hmmptr)(int) = hmm; (*fptr)((int)hmmptr); return 0; } I don't really understand the code above, i have it from an online game - i should supply something in the arguments so it would give me shell, but i don't get it how it works so i don't know what to do. So i need someone that would explain it what it does, how it's working and the stuff. Thanks.

  • formatting an array of mobile numbers

    - by Kyle Hudson
    Hi, I am creating a SMS app the following code is supposed to: check if the mobile/cell number is 11 characters long. check if the number starts with 07. If neither of these conditions are met, it should remove the number from the array. So the following numbers would be valid: 07123456789,07123456790,07123456791,07123456792,07123456793,07123456794 However the following wouldn't (and need to be removed): 0801458,07855488,6695522214124514 $param["number"] = "07123456789,07123456790,07123456791,07123456792,07123456793,07123456794,0801458,07855488,6695522214124514"; $number = explode(',', $param["number"]); foreach($number as $num){ if (!substr_compare($num, "07", 0, 3, false)) { unset($num); } elseif (substr_compare($num, "07", 0, 3, true)) { if(strlen($num) == 11) { $li .= "447" . substr($num, 2) . ','; } } } $il .= substr($li, 0, strlen($li)-1); echo $il; // $request = substr($request, 0, strlen($request)-1); // return $n; } I also need to remove the final comma from the result. Any help will be appriciated. Thanks, Kyle

  • How to map (large) integer on (small in size( alphanumeric string with PHP? (Cantor?)

    - by Glooh
    Dear all, I can't figure out how to optimally do the following in PHP: In a database, I have messages with a unique ID, like 19041985. Now, I want to refer to these messages in a short-url service but not using generated hashes but by simply 'calculate' the original ID. In other words, for example: http://short.url/sYsn7 should let me calculate the message ID the visitor would like to request. To make it more obvious, I wrote the following in PHP to generate these 'alphanumeric ID versions' and of course, the other way around will let me calculate the original message ID. The question is: Is this the optimal way of doing this? I hardly think so, but can't think of anything else. $alphanumString = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-_'; for($i=0;$i < strlen($alphanumString);$i++) { $alphanumArray[$i] = substr($alphanumString,$i,1); } $id = 19041985; $out = ''; for($i=0;$i < strlen($id);$i++) { if(isset($alphanumString["".substr($id,$i,2).""]) && strlen($alphanumString["".substr($id,$i,2).""]) 0) { $out.=$alphanumString["".substr($id,$i,2).""]; } else { $out.=$alphanumString["".substr($id,$i,1).""]; $out.=$alphanumString["".substr($id,($i+1),1).""]; } $i++; } print $out;
