Description:
------------
<?php
$str = '<!--b>here!</b-->';
print strip_tags($str);
?>
in PHP 4.2.2 it outputs 'here!'.
in PHP 4.3.4 it outputs nothing.
Maybe it should be treated as the right behavior, but it is definitely a BC violation.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Who the heck gets in trouble with the new behaviour?

I found an old script that had relied on the old behavior (which was "strip everything between &lt; and &gt;",  e.g. http://bugs.php.net/bug.php?id=15160) and broken under PHP 4.3.4. 
I would think of it at least as a documentation problem, not bogus. Don't you think that every php developer in the World would read this message to answer your question, even if he gets in trouble with the new behavior? The things that break BC should at least be documented. But there's no a word even in the Changes file.

Okay, I had missed that report and now noticed it was 
recognised wrongly. Anyway, I agree with you that 
strip_tags() is not well documented and it's the right 
time to add an extensive description because too many 
users rely on this magical function. Reclassifying this 
as a documentation problem.

Can somebody check when strip_tags() changed its behaviour, please?
I couldn't find this in CVS logs...

[2004-01-27 10:41 UTC] nlopess@php.net

I've checked the sources and the behaviour changed in PHP 4.3.0. I'll update the docs.

[2004-01-27 10:56 UTC] nlopess@php.net

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
