ID: 27021 Updated by: nlopess@php.net Reported By: mderk at yandex dot ru -Status: Open +Status: Analyzed Bug Type: Documentation problem -Operating System: FreeBSD +Operating System: Irrelevant -PHP Version: 4.3.4 +PHP Version: 4.3.0 -Assigned To: +Assigned To: nlopess New Comment: I've checked the sources and the behaviour changed in PHP 4.3.0. I'll update the docs. Previous Comments: ------------------------------------------------------------------------ [2004-01-26 13:43:56] nlopess@php.net Can somebody check when strip_tags() changed its behaviour, please? I couldn't find this in CVS logs... ------------------------------------------------------------------------ [2004-01-26 07:25:58] moriyoshi@php.net 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. ------------------------------------------------------------------------ [2004-01-26 02:57:51] mderk at yandex dot ru 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. ------------------------------------------------------------------------ [2004-01-23 17:11:09] moriyoshi@php.net 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? ------------------------------------------------------------------------ [2004-01-23 10:43:10] mderk at yandex dot ru 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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27021&edit=1
