    <p>I am combining all my javascriupt into one neat file in order to lower http requests! Im stuck removing the comments <code>/* comments */</code> and <code>// comments</code>. My level is by far below minification or parsing stuff. I know how to make macaroni strings. Anything more complex than that, you will not find in my computer or kitchen, SO:</p> <h1>QUESTION</h1> <p>meanwhile at combining it to one file, i want to remove all comments.<br> <strong>What is the correct regex for this?</strong></p> <pre><code>&lt;?php header('Content-type: text/javascript'); $offset = 60 * 60 * 24; // Cache for a day header ('Cache-Control: max-age=' . $offset . ', must-revalidate'); header ('Expires: ' . gmdate ("D, d M Y H:i:s", time() + $offset) . ' GMT'); ob_start("compress"); function compress($buffer) { # NOT SURE, not all new lines are removed?? # remove tabs, spaces, newlines, etc. $buffer = str_replace(array("\r\n", "\r", "\t", ' ', ' '), '', $buffer); # WORKS !!! # remove comments / XXXXXXX $buffer = preg_replace('(// .+)', '', $buffer); ######################################################################## # !! STUCK HERE !! OUTPUT FILE LOOKS OK BUT WEBSITE DOESNT LOAD OK IF THIS IS ON # remove comments / * XXX (enters etc) XXXX * / # $buffer = preg_replace('#/\*(?:.(?!/)|[^\*](?=/)|(?&lt;!\*)/)*\*/#s', '', $buffer); ######################################################################## return $buffer; } include('../file1.js'); include('../file2.js'); ob_end_flush(); ?&gt; </code></pre> <p>It would be great if it would catch and delete the following:</p> <pre><code>/* XXXX */ /* XXXX XXXX */ </code></pre> <p>Thats all! Cant get it to work nomatter what regex i use even with this incredible tool, where i FOUND the right match to be:</p> <pre><code>RegExp: /\/\*(?:.(?!/)|[^\*](?=/)|(?&lt;!\*)/)*\*\//gs pattern: \/\*(?:.(?!/)|[^\*](?=/)|(?&lt;!\*)/)*\*\/ flags: gs </code></pre> <p><a href="http://gskinner.com/RegExr/" rel="nofollow">http://gskinner.com/RegExr/</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
