Replace php tags with #

Copy linkTweet thisAlerts:

Hi folks,
I have got a textarea and some html/php code in it. What I want to do is replace php tags with # symbol. Here’s what I got:

[CODE]
sourceCode.replace(/<?php .* ?>/g, “#”);
[/CODE]

but if code textarea content looks like this
[b]<a href=”<?php echo $link; ?>” title=”<?php echo $title; ?>”><?php echo $link; ?></a>[/b]
the result is following
[b]<a href=”#</a>[/b]
while it should look like this
[b]<a href=”#” title=”#”>#</a>[/b]

How to correct this issue?

/&lt;?php [^&gt;]+ ?&gt;/g

/&lt;?(.|n|r)+??&gt;/

@ninkyauthorMay 14.2009 — Hmm, what about unhide() function?

If I hide php tags and then modify some html, I click "show php tags" and it returns me php tags but with unmodified html. Do I need to store php tags in some special array or var, in order to unhide them?

@felgallMay 14.2009 — How are you planning for the JavaScript to even see the PHP tags. The usual order for processing is that the PHP runs first generating HTML and the JavaScript runs against the HTML that the PHP generated.
