• Generate Windows .lnk file with PHP

  - by Andrei

  Hello, I'm working on a project which involves an FTP server running ProFTPd and a PHP/MySQL backend that creates accounts for users. Upon the creation of accounts, users are sent e-mails with their account details and instructions for downloading FileZilla or CyberDuck, depending on their OS, detected via user-agent string. To make things easier for novices, I thought of having .lnk files generated for FileZilla with the account logins details as parameters, so they would just have to click on the .lnk files to open up the server. This is not crucial feature but more of a technical challenge. My questions are : is this even feasible ? are there any alternatives (eg. generating a .bat with a script pointing to the Filezilla executable ?) are there any issues, perhaps with relative / absolute paths pointing to the executable ? to go even further, what would be the simplest way of providing users with software with FTP access on a single account / single server (web interface is not an option).

• How does PHP's list function work?

  - by Jacob Relkin

  After recently answering a couple of questions here on SO that involved utilizing PHP's list function, I wondered, "how in the world does that function actually work under the hood?". I was thinking about something like using func_get_args() and then iterating through the argument list, and that's all nice and peachy, but then how in the world does the assignment part work? list(...) = array($x, $y, $z); isn't this ^ evaluated first? So to be precise, my question is how is the list function able to create scoped variables which get assigned to the not-yet evaluated array?

• PHP - What to store in a session?

  - by eWolf

  I know about all the issues with session fixation and hijacking. My question is really basic: I want to create an authentication system with PHP. For that, after the login, I would just store the user id in the session. But: I've seen some people do weird things like generating a GUID for each user and session and storing that instead of just the user id in the session. Why? The content of a session cannot be obtained by a client - or can it?

• Setting up path mapping in PHP and Eclipse

  - by jax

  I have just setup my website locally so I can test my pages more easily. Eclipse has been configured to use an XAMPP server locally. The problem is that I want to map my project to a certain place in my website. ie. In my Eclipse PHP project I have a folder called com I want this to map to /com in the webstie. I tried to do this in the mapping section of the Eclipse server setup but it didn't work. When I type http://localhost/com/ It should go to my project folder, however, when I type other folder it should use the normal website folders. how can I do this?

• PHP complete sample website source

  - by MarceloRamires

  I'm new to PHP, and it appears that the way I learn the fastest is to study a new language a well developed complete program (or website, in this case) changing stuff seeing what happens and consulting books. There are lots of recommendations of books all around, and that's pretty much covered. I'd like to find the sourcecode of a website. Either a well known, well developed open-source website, or a sample sourcecode of a complete website (maybe one used in a book or something). Everyone says they should find the way they learn better.. Well, that's mine. PS.: By complete I mean having several common functionalities (such as login), database connection, use of security conventions, maybe a popular framework, and being up-to-date.

• php search and replace

  - by Dave

  I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

• Caching HTML output with PHP

  - by Mohamed Amine

  Hi! I would like to create a cache for my php pages on my site. I did find too many solutions but what I want is a script which can generate an HTML page from my database ex: I have a page for categories which grabs all the categories from the DB, so the script should be able to generate an HTML page of the sort: my-categories.html. then if I choose a category I should get a my-x-category.html page and so on and so forth for other categories and sub categories. I can see that some web sites have got URLs like: wwww.the-web-site.com/the-page-ex.html even though they are dynamic. thanks a lot for help

• Posting within PHP and receiving only cookie

  - by faya

  Hello I have a question. It might be sound ridiculous, but let me explain what I want to accomplish. Right now I try to embed open source forum to by site and I want to leave forum and my site databases split. When my site users are logging in I want them also automatically be logged in to the forum system. For that I want to login within my PHP code after receiving username and password in post, but I don't know how I can get only cookies in response. I have found out that I can use curl_init(), curl_exec(), curl_close() functionality, but response from curl_exec returns whole response(page content, cookies, headers). Is there a way to receive only cookies? P.S. - If my design is totally wrong please give an advise how I can embed this functionality! I would be very thankful!

• Connecting a PHP front-end to a back-end java service

  - by christopher-mccann

  I am currently using various back-end services and I want to use PHP to simply query these services and perform the final page construction. These services could be coded in any number of programming langauges such as Erlang, Java, Python etc. However I am unsure of the best way to actually interface the back-end services with the web app. Requests to these services would be both synchronous and asynchronous. Would I use something like SOAP or JSON-RPC?? Any help greatly appreciated.

• recaptcha image and curl + php

  - by user253530

  $page = $curl->post($baseUrl.'/submit.php', array('url'=>$address,'phase'=>'1','randkey'=>$randKey[0],'id'=>'c_1')); $exp = explode('recaptcha_image',$page); The id recaptcha_image is not found although if i echo $page; the webpage will be displayed and surprisingly even the recpatcha div (with the image itself). Curl shouldn't load the image for recaptcha but somehow it does though when i try to find the div, it is not there. Is there a way to capture the url of the recaptcha image?

• ready to use design pattern APIs for PHP?

  - by ajsie

  i know that in Java you can use their built-in APIs for design pattern. eg. if you want to use the observer pattern, you just have to extend your Subject class with the Observable class. is this possible for PHP? are there any libraries for the design patterns ready to use. in this way you don't have to reinvent the wheel and you also let many developers follow a standard. does Zend library have these API:s?

• Fastest PHP Routine To Match Words

  - by Volomike

  What is the fastest way in PHP to take a keyword list and match it to a search result (like an array of titles) for all words? For instance, if my keyword phrase is "great leather shoes", then the following titles would be a match... Get Some Really Great Leather Shoes Leather Shoes Are Great Great Day! Those Are Some Cool Leather Shoes! Shoes, Made of Leather, Can Be Great ...while these would not be a match: Leather Shoes on Sale Today! You'll Love These Leather Shoes Greatly Great Shoes Don't Come Cheap I imagine there's some trick with array functions or a RegEx (Regular Expression) to achieve this rapidly.

• php - track down premature headers leak

  - by user151841

  I'm using set_cookie() on a site. After adding some functionality, I'm getting Warning: Cannot modify header information - headers already sent by... error. The line number it references as to where the headers initiated from is the very line where set_cookie() is! And I checked, it's not being called twice. How can I track down these premature headers? I looked at the source code and didn't see any stray characters or anything before the error message starts ( I'm using xdebug, so the first thing is a , which I thought was me, but is actually the beginning of the xdebug message ). I've grepped my code for extra echo and so forth -- nothing. Can PHP tell me when and where the headers are starting? Or are they really starting on the set_cookie line, and if so, how have I gotten myself into this situation, and how do I get out?

• Preg_match class name from PHP file

  - by talentedmrjones

  I have a script that recursively scans a directory pulling out class names from php files, and storing those classes names in an array. This is working nicely even through the rather large Zend Framework library folders. The issue is that classes that extend other classes are not being included in the array. Here is my current preg_match: if (preg_match("/class\s*(\w*)\s*\{/i",strip_comments(file_get_contents($file)),$matches)) $classes[] = $matches[1]; I know that the last \s* is not right; there should be something there that can catch "{" or " extends Some_Other_Class {" .

• PHP: detecting IP's entry to a specific IP range

  - by ilnur777

  I have the PHP function that determines whether one IP goes to a specific IP range, but I don't know how to find out the IP's network and mask. Can anyone help with this? <? // Example of calling and checking IP-address 192.168.0.4 // belonging to a network 192.168.0.0 with mask 255.255.255.248 if(ip_vs_net("192.168.0.4","192.168.0.0","255.255.255.248")){ print "Address belongs to a netwok<BR>"; } else { print "Address is out of subnetwork's range<BR>"; } function ip_vs_net($ip,$network,$mask){ if(((ip2long($ip))&(ip2long($mask)))==ip2long($network)){ return 1; } else { return 0; } } ?>

• PHP/MySQL: Storing and retrieving UUIDS

  - by Greg

  I'm trying to add UUIDs to a couple of tables, but I'm not sure what the best way to store/retrieve these would be. I understand it's far more efficient to use BINARY(16) instead of VARCHAR(36). After doing a bit of research, I also found that you can convert a UUID string to binary with: UNHEX(REPLACE(UUID(),'-','')) Pardon my ignorance, but is there an easy way to this with PHP and then turn it back to a string, when needed, for readability? Also, would it make much difference if I used this as a primary key instead of auto_increment? EDIT: Found part of the answer: $bin = pack("h*", str_replace('-', '', $guid)); How would you unpack it?

• Comparing two ISO8601 dates strings in PHP

  - by oompahloompah

  I need to compare (actually rank/sort) dates in a PHP script. The dates are ISO-8601 Date format i.e. YYYY-MM-DD I wrote a comparison function which splits the dates and compares by year/month/day. However, it seems this may be overkill and I could just as easily done a simple string comparison like: if ($date1 < $date2) // do something elseif( $date1 > $date2) //do something else else //do yet another thing Is my assumption about (ISO-8601) Date string comparison correct - i.e. can I get rid of my function (to save a few clock cycles on the server), or is it safer to explicity do the comparison in a custom function?

• Real time web site using PHP or ASP.NET

  - by Roman

  Hey Guys, I'm looking for a way to put real time features into my web site. The idea is asynchronous communication between 2 people - like a chat session. If I use the chat example - I'd like the second person to know that the first one has sent a message to him, without refreshing or doing something active on the web page. Polling is not a good idea here - so is there any other solution? the back-end could be ASP.NET or PHP (ASP.NET preferred). Help would be much appreciated, Thanks, Roman

• PHP: Iterate through folders and display HTML contents

  - by Mestika

  Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function.

• PHP: Prevent chained method from returning?

  - by Industrial

  Hi, I am having some headaches regarding method chaining for a quite simple PHP class that returns a value, which sometimes need to go through a decryption process: $dataset = new Datacontainer; $key = $dataset->get('key'); $key2 = $dataset->get('key')->decrypt(); The get method is where the return lives. So the call to the decrypt method on the second row isn't going to work in its current state. Can I do something to setup the get method to return only when nothing is chained to it, or what would be the best way to re-factor this code?
