  • Does the deprecation of mysql_* functions in PHP carry over to other Databases(MSSQL)?

    - by MobyD
    I'm not talking about MySQL, I'm talking about Microsoft SQL Server I've been aware of PDO for quite some time now, standard mysql functions are dangerous and should be avoided. http://php.net/manual/en/function.mysql-connect.php But what about the MSSQL function in PHP? They are, for most purposes, identical sets of functions, but the PHP page describing mssql_* carries no warning of deprecation. http://us.php.net/manual/en/function.mssql-connect.php There are PDO drivers available for MSSQL, but they aren't quite as readily available or used as the MySQL drivers. Ideally, it looks to me like I should get them working and move from mssql_* to PDO like I have with MySQL, but is it as big of a priority? Is there some hidden safety to MSSQL that means it's exempt from all of the mysql_* hatred as of late? Or is its obscurity as a backend the only reason there hasn't been more PDO encouragement?

  • Why does PHP create these log entries on every page access?

    - by HXCaine
    My server's error log (in cPanel) has an entry for every single time a PHP page is loaded that looks like this (where 'username' has been substituted for my actual username): [2012-06-09 09:02:07]: info: [usr/grp]: username/username cmd: /home/username/public_html/error.php php: /usr/local/php53/bin/php I know it's only an 'info' message but it's filling up my error log. It can't be related to the content of my PHP files because it even happens when I load a page with this as its content: <?php phpinfo(); ?> Any ideas on what it means or if I can get rid of it?

  • What features would you like to have in PHP? [closed]

    - by StasM
    Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

  • How to use different php.ini files for different VirtualHosts?

    - by gsingh2011
    I have my site and it's staging subdomain running on the same CentOS machine running apache. The subdomain is created using a VirtualHost, and I use it to find any bugs before I push to production. I want the php.ini file for the staging VirtualHost to be a development one, and the production site will use a production php.ini. How can I configure apache to use different php.ini files? I don't want to use php_value/php_flag for everything, I'd rather just use the php.ini file I already have available. I've tried creating an .htaccess file that looks like this, SetEnv PHPRC /path/to/php.ini/directory This has no effect, as phpinfo() tells me it's still using /etc/php.ini. I've also tried setting PHPIniDir for both virtual hosts (www and staging) and it complains about seeing the directive twice.

  • Is "PHP and MySQL Web Development, 4th ed." an outdated book to learn from?

    - by ForeverLearnNeverMaster
    I want to get into web stuff, and thought of going with PHP+MySQL. I have experience in C#, C++, desktop graphics, but no web stuff besides HTML, CSS which I started learning 2 months ago. On SO PHP-book question, the highest rated book is "PHP Objects, Patterns and Practice". However, I'm not sure if it's a book to start PHP with... or is it? Most of the books mentioned in that SO question seem to be for those who already know PHP. I considered "PHP & MySQL Web Development, 4th Ed.", but someone mentioned that "it uses the mysql_* functions which are almost deprecated." Help?

  • How do I pitch ASP.NET over PHP to a potential client?

    - by roman m
    I work at a Microsoft shop doing mainly web development. We had a client who asked us to review (improve) the data model for his web app, but said that he wants to develop his app in PHP (he knows "a guy" who can do it). When I asked him why he wants to go with PHP, he gave me the standard set of arguments from the 90's: Microsoft is evil, and PHP is free Writing an ASP.NET app is more expensive (software-wise) Why would Facebook use PHP if it was a bad idea? [classic] He had a few more comments about the costs associated with going .NET. The truth is that "Microsoft is expensive" does not hold water any longer, with their "Express" suite, you can develop an ASP.NET app without paying anything for software. When it comes to hosting, you can save a few bucks with PHP over .NET, but that's a small fraction of the projected development costs (we quoted 10-15k). Going back to my question, what arguments would I give to a client in favor of ASP.NET over PHP? [please provide sources for quantitative claims]

  • Consistent PHP _SERVER variables between Apache and nginx?

    - by Alix Axel
    I'm not sure if this should be asked here or on ServerFault, but here it goes... I am trying to get started on nginx with PHP-FPM, but I noticed that the server block setup I currently have (gathered from several guides including the nginx Pitfalls wiki page) produces $_SERVER variables that are different from what I'm used to seeing in Apache setups. After spending the last evening trying to "fix" this, I decided to install Apache on my local computer and gather the variables that I'm interested in under different conditions so that I could try and mimic them on nginx. The Apache setup I've on my computer has only one mod_rewrite rule: RewriteEngine On RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 [L] And these are the values I get for different request URIs (left is Apache, right is nginx): localhost/ - http://www.mergely.com/GnzBHRV1/ localhost/foo/bar/baz/?foo=bar - http://www.mergely.com/VwsT8oTf/ localhost/index.php/foo/bar/baz/?foo=bar - http://www.mergely.com/VGEFehfT/ What configuration directives would allow me to get similar values on requests handled by nginx? My current configuration in nginx is: server { listen 80; listen 443 ssl; server_name default; ssl_certificate /etc/nginx/certificates/dummy.crt; ssl_certificate_key /etc/nginx/certificates/dummy.key; root /var/www/default/html; index index.php index.html; autoindex on; location / { try_files $uri $uri/ /index.php; } location ~ /(?:favicon[.]ico|robots[.]txt)$ { log_not_found off; } location ~* [.]php { #try_files $uri =404; include fastcgi_params; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_split_path_info ^(.+[.]php)(/.+)$; } location ~* [.]ht { deny all; } } And my fastcgi_params file looks like this: fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param HTTPS $https; I know that the try_files $uri =404; directive is commented and that it is a security vulnerability but, if I uncomment it, the third request (localhost/index.php/foo/bar/baz/?foo=bar) will return a 404. It's also worth noting that my PHP cgi.fix_pathinfo in On (contrary to what some of the guides recommend), if I try to set it to Off, I'm presented with a "Access denied." message on every PHP request. I'm running PHP 5.4.8 and nginx/1.1.19. I don't know what else to try... Help?

  • Vim: Context sensitive code completion for PHP

    - by eddy147
    Vim gives me too much options when I use code completion. In a class, and type $class- it gives me about a zillion options, so not only from the class itself but also from php, all globals ever created, in short: a mess. I only want to have the options from the class itself (or the parent subtype class it extends from), so context or scope sensitive code completion, just like Netbeans for example. How can I do that? My current configuration is this: I am using ctags, and created 1 ctags file for our (big) application in the root. This is the .ctags file I used to create the ctags file: -R -h ".php" --exclude=.svn --languages=+PHP,-JavaScript --tag-relative=yes --regex-PHP=/abstract\s+class\s+([^ ]+)/\1/c/ --regex-PHP=/interface\s+([^ ]+)/\1/c/ --regex-PHP=/(public\s+|static\s+|protected\s+|private\s+)\$([^ \t=]+)/\2/p/ --regex-PHP=/const\s+([^ \t=]+)/\1/d/ --regex-PHP=/final\s+(public\s+|static\s+|abstract\s+|protected\s+|private\s+)function\s+\&?\s*([^ (]+)/\2/f/ --PHP-kinds=+cdf --fields=+iaS This is the .vimrc file: " autocomplete funcs and identifiers for languages autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType python set omnifunc=pythoncomplete#Complete autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS autocmd FileType html set omnifunc=htmlcomplete#CompleteTags autocmd FileType css set omnifunc=csscomplete#CompleteCSS autocmd FileType xml set omnifunc=xmlcomplete#CompleteTags autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType c set omnifunc=ccomplete#Complete " exuberant ctags " the magic is the ';' at end. it will make vim tags file search go up from current directory until it finds one. set tags=projectrootdir/tags; map <F8> :!ctags " TagList " :tag getUser => Jump to getUser method " :tn (or tnext) => go to next search result " :tp (or tprev) => to to previous search result " :ts (or tselect) => List the current tags " => Go back to last tag location " +Left click => Go to definition of a method " More info: " http://vimdoc.sourceforge.net/htmldoc/tagsrch.html (official documentation) " http://www.vim.org/tips/tip.php?tip_id=94 (a vim tip) let Tlist_Ctags_Cmd = "~/bin/ctags" let Tlist_WinWidth = 50 map <F4> :TlistToggle<cr> "see http://vim.wikia.com/wiki/Make_Vim_completion_popup_menu_work_just_like_in_an_IDE " will change the 'completeopt' option so that Vim's popup menu doesn't select the first completion item, but rather just inserts the longest common text of all matches :set completeopt=longest,menuone " will change the behavior of the <Enter> key when the popup menu is visible.

  • Suhosin per-URL exceptions?

    - by STATUS_ACCESS_DENIED
    I am using SimpleID as my OpenID provider and it turns out that if I log on via pages like those on StackExchange, one of the parameters of the GET request gets dropped by Suhosin. The name of the variable is s and I presume it's responsible for the "return to URL" part after login. All of this is not a problem as long as I am already logged into SimpleID from before. However, as soon as the site on which I want to log in via OpenID ends up at the login screen of SimpleID, the redirect back to the site I came from does not work anymore due to the dropped variable. Is there a method to configure either on a per-virtual-host or per-URL basis to ignore the maximum length for GET requests with a parameter s exceeding the (globally) set limit? I'm using Apache 2.2, so I was wondering whether a mechanism similar to setting the PHP ini variables from within the server configuration exists for Suhosin.

  • How to check a complex condition in Smarty(PHP)

    - by php html
    I need to display a section or another in a smarty template. My condition is simple: if a smarty value starts with a string I should display one section, otherwise the other smarty section should be displayed. I can change only the tpl files. {php} if (substr($url,0,4) != 'http') { {/php} section 1 {php} } else { {/php} section 2 {php} } {/php} The problem is that I can not read the url varible which was previously assigned using $smarty-assign. Basically, I'm looking for the smarty function that can be used to retrieve a value, or if there is a better solution.

The algorithm programmer built the algorithm in python. The developers refuse to finish the app because they say it won't work with python, while the programmer insist it will. The programmer says put the algorithm in its on server and connect then over http. Will this work and I'd so how risky is it to future problems?

Eclipse is okay but i cant fold if/while blocks and slow. Gedit can be extended and i have tried it but still i could not fold code or show error. I currently use Geany but it doesn't inform me of syntax errors as i type. If you have ways to solve the problems with above editors they too are also welcome

  • PHP security regarding login

    - by piers
    I have read a lot about PHP login security recently, but many questions on Stack Overflow regarding security are outdated. I understand bcrypt is one of the best ways of hashing passwords today. However, for my site, I believe sha512 will do very well, at least to begin with. (I mean bcrypt is for bigger sites, sites that require high security, right?) I´m also wonder about salting. Is it necessary for every password to have its own unique salt? Should I have one field for the salt and one for the password in my database table? What would be a decent salt today? Should I join the username together with the password and add a random word/letter/special character combination to it? Thanks for your help!

  • How to build a Singleton-like dependency injector replacement (Php)

    - by Erparom
    I know out there are a lot of excelent containers, even frameworks almost entirely DI based with good strong IoC classes. However, this doesn't help me to "define" a new pattern. (This is Php code but understandable to anyone) Supose we have: //Declares the singleton class bookSingleton { private $author; private static $bookInstance; private static $isLoaned = FALSE; //The private constructor private function __constructor() { $this->author = "Onecrappy Writer Ofcheap Novels"; } //Sets the global isLoaned state and also gets self instance public static function loanBook() { if (self::$isLoaned === FALSE) { //Book already taken, so return false return FALSE; } else { //Ok, not loaned, lets instantiate (if needed and loan) if (!isset(self::$bookInstance)) { self::$bookInstance = new BookSingleton(); } self::$isLoaned = TRUE; } } //Return loaned state to false, so another book reader can take the book public function returnBook() { $self::$isLoaned = FALSE; } public function getAuthor() { return $this->author; } } Then we get the singelton consumtion class: //Consumes the Singleton class BookBorrower() { private $borrowedBook; private $haveBookState; public function __construct() { this->haveBookState = FALSE; } //Use the singelton-pattern behavior public function borrowBook() { $this->borrowedBook = BookSingleton::loanBook(); //Check if was successfully borrowed if (!this->borrowedBook) { $this->haveBookState = FALSE; } else { $this->haveBookState = TRUE; } } public function returnBook() { $this->borrowedBook->returnBook(); $this->haveBookState = FALSE; } public function getBook() { if ($this->haveBookState) { return "The book is loaned, the author is" . $this->borrowedbook->getAuthor(); } else { return "I don't have the book, perhaps someone else took it"; } } } At last, we got a client, to test the behavior function __autoload($class) { require_once $class . '.php'; } function write ($whatever,$breaks) { for($break = 0;$break<$breaks;$break++) { $whatever .= "\n"; } echo nl2br($whatever); } write("Begin Singleton test", 2); $borrowerJuan = new BookBorrower(); $borrowerPedro = new BookBorrower(); write("Juan asks for the book", 1); $borrowerJuan->borrowBook(); write("Book Borrowed? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); write("Juan returns the book", 1); $borrowerJuan->returnBook(); write("Returned Book Juan? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks again for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); This will end up in the expected behavior: Begin Singleton test Juan asks for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels Pedro asks for the book Book Borrowed? I don't have the book, perhaps someone else took it Juan returns the book Returned Book Juan? I don't have the book, perhaps someone else took it Pedro asks again for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels So I want to make a pattern based on the DI technique able to do exactly the same, but without singleton pattern. As far as I'm aware, I KNOW I must inject the book inside "borrowBook" function instead of taking a static instance: public function borrowBook(BookNonSingleton $book) { if (isset($this->borrowedBook) || $book->isLoaned()) { $this->haveBook = FALSE; return FALSE; } else { $this->borrowedBook = $book; $this->haveBook = TRUE; return TRUE; } } And at the client, just handle the book: $borrowerJuan = new BookBorrower(); $borrowerJuan-borrowBook(new NonSingletonBook()); Etc... and so far so good, BUT... Im taking the responsability of "single instance" to the borrower, instead of keeping that responsability inside the NonSingletonBook, that since it has not anymore a private constructor, can be instantiated as many times... making instances on each call. So, What does my NonSingletonBook class MUST be in order to never allow borrowers to have this same book twice? (aka) keep the single instance. Because the dependency injector part of the code (borrower) does not solve me this AT ALL. Is it needed the container with an "asShared" method builder with static behavior? No way to encapsulate this functionallity into the Book itself? "Hey Im a book and I shouldn't be instantiated more than once, I'm unique"
