Regex newbie here. There's a (broken) plugin for the forum software I use that I'm attempting to fix. It's generating the following regex:\[code\]/(?:\s|^)\[(?:\:\)\]|;\)\])(?:\s|$)/m\[/code\]... to replace all instances of \[code\][
]\[/code\] or \[code\][
]\[/code\] in a block of text using \[code\]preg_replace()\[/code\]. However, it's not replacing the instances of \[code\][]\[/code\] or \[code\][]\[/code\]. Any ideas?EDIT: The plugin in question is Emoticons, for Vanilla. Here's the code (irrelevant sections and e-mail addresses removed):\[code\]\[code\] // Build an Array containing the Emoticon<-->Graphic matches if (!isset($EmoticonMatch)) { $EmoticonMatch = array( '[]' => 'smile.gif', '[]' => 'wink.gif', ); // Add more matches, if you need them... Put the corresponding graphics into the Plugin's images-folder } // In case there's something wrong with the Array, exit the Function if (count($EmoticonMatch) == 0) return; // Define the basic Regex pattern to find Emoticons $EmoticonsSearch = '/(?:\s|^)'; // Automatically extend the Regex pattern based on the Emoticon-Codes in the $EmoticonMatch-Array $subchar = ''; foreach ( (array) $EmoticonMatch as $Smiley => $Img ) { $firstchar = substr($Smiley, 0, 1); $rest = substr($Smiley, 1); // new subpattern? if ($firstchar != $subchar) { if ($subchar != '') { $EmoticonsSearch .= ')|(?:\s|^)'; } $subchar = $firstchar; $EmoticonsSearch .= preg_quote($firstchar, '/') .
