// and ?>

<?php

//?>

echo "hello";

?>

I'm running PHP 5.24 and When I run that script it displays the source after //?>. So it seems that ?> ignores the fact its commented out.

Strange...

FWIW: it appears that the "?>" is suppressed when within a /.../ comment block, however.

I noticed that. If I wasn't about to go to bed I'd check #.

I came across it when it happened I had a reg-ex with ?> in it the string and I commented the line out. I was very puzzled briefly.

This is actually the documented behaviour 🙂

In a way, it sort of makes sense, as it allows you to comment php code inserted inline with HTML text:

<p>The value is <?php echo $value; // a comment here ?>.</p>

I guessed it was what was supposed to happen. So that must mean PHP parses comments?

I was just caught out when I wanted to comment out the below line as I put a copy of my regex in a comment while I made a change to it. Then suddenly the rest of my code was being displayed on the screen!

// $match = "/<\/?\w+((\s+(\w|\w[\w-]*\w)(\s*=\s*(?:\".*?\"|'.*?'|[^'\">\s]+))?)+\s*|\s*)\/?>/i";

Well, it would have to, wouldn't it? To find where they end... 🙂
