Hi, I have been using the following regex for BB code on several occasions and that’s the first time to run into problem like this. The problem occurred when I added code tag for code highlight using Geshi. The code I’m using is: while (preg_match('#\[(.+)(?:=(.*?))?\](.*?)\[\/\1\]#s',$text)) { $text = preg_replace_callback('#\[(.+)(?:=(.*?))?\](.*?)\[\/\1\]#s', 'parse_bb_callback', $text); } The problem is, that on some occasions it fails to find any tags in string even though they are there. I can’t figure out why. I’ll just copy 2 random posts contents from my forum to demonstrate the matter. Following post gets parsed perfectly: [quote=Autor]Quote content[/quote] Text content [code=HTML]<div class="art-post"> <div class="art-post-body"> <div class="art-post-inner"> <div class="art-postmetadataheader"> <h2 class="art-postheader"><img src="/templates/vannisalong1/images/postheadericon.png" alt="postheadericon" width="30" height="30" /> Valamud </h2> </div> <div class="art-postcontent"> <!-- article-content --> <div class="art-article"><p> </p> <table align="center" border="0"> <tbody> <tr> <td><a target="_blank" href="http://www.ravak.ee/?page=ppu"><img height="190" width="220" src="/images/stories/Ravak/ravakvalamu.jpg" alt="ravakvalamu" /></a></td> <td><a target="_blank" href="http://paavannid.ee/index.php?sub=valamud"><img height="190" width="220" src="/images/stories/Paa/paavalamu.jpg" alt="paavalamu" /></a></td> </tr> <tr> <td> <a target="_blank" href="http://www.ravak.ee/?page=ppu">RAVAK valamud</a></td> <td> <a target="_blank" href="http://paavannid.ee/index.php?sub=valamud">PAA valamud</a></td> </tr> </tbody> </table> More text border:1px solid #4A691C; More text [/code] However, if I add [code=CSS].art-post { margin:5px; } .art-post { margin:0 auto; min-height:1px; min-width:1px; position:relative; z-index:0; } .art-post-body { padding:15px; position:relative; z-index:1; } .art-postmetadataheader { background-color:#D3E9C3; padding:1px; } .art-postheader { color:#1C2D11; font-size:26px; margin:0.2em 0; padding:0; } .art-postcontent { letter-spacing:1px; line-height:125%; margin-left:5px; margin-right:5px; text-align:justify; } [/code] It won’t render a single tag and 'parse_bb_callback won’t execute even once. Thereby I conclude that the problem must be in the regular expression, but what exactly? Nested quotes work, several code tags in one post also work in other posts. What could be causing it to fail on so few occasions?

$string = 'NULL'; foreach ( $_POST as $item ) { $string .= " \'$item\'"; } echo $string;

On line: "if ( $reason = "Interact is not open it opens at 4.pm and closes at 8 pm" ) { " you assign value to $reason variable instead of comparing it. You need to use ==.

In that case, why not to use sessions instead of cookies?

During first iteration the loop prints out the default values of the variables. Values are added once the loop has executed at least once.

Like thorpe said there is no now() function in PHP. However there is time(), which return current timestamp. So, if you want to get current time use $current = time(); And if you want to add 15 minutes to it just add 15*60 to it.

You could encrypt the password using md5().

I don't know what you exactly mean by username=$username, but if ( ($time > (time()-30)) && ($username == 'sth') ) {} The code gets executed, if the value of $time is less than 30 seconds compared to present time and username equals the one you want.

What exactly do you mean with calling session from previous page? And yes, you can implement given code like that

Try using session_unset() before session_destroy()

Do you have session_start() at the beginning of the file you are using this code at? Edited: Apparently not. Add it and both, unset and session_destroy() should work.

What you are currently doing is assigning value 'logout' to $_GET['action']. Actually the solution is really easy if ($_GET['action'] == "logout")
