Doc #69584 [Com]: strip_tags: meaning of $allowable_tags reverted

Edit report at https://bugs.php.net/bug.php?id=69584&edit=1 ID: 69584 Comment by: peehaa@php.net Reported by: cmb@php.net Summary: strip_tags: meaning of $allowable_tags reverted Status: Open Type: Documentation Problem Package: Strings related Operating System: * PHP Version: Irrelevant Block user comment: N Private report: N New Comment: You are right Chris. Self-closing tags in the allowable_tags param are simply ignored and non-self-closing tags also preserve self-closing tags as it should. Previous Comments: ------------------------------------------------------------------------ [2015-09-02 00:34:45] cmb@php.net Related To: Bug #70402 ------------------------------------------------------------------------ [2015-07-26 13:37:39] chris at ocportal dot com I found this too. As far as I can tell this note, and the note in the changelog, are 100% nonsense. The parameter is for allowable, not preserved. But also, it doesn't seem to have any truth whatsoever to it. echo strip_tags('<br><br />','<br>'); produces "<br><br />". echo strip_tags('<br><br />',''); produces "". i.e. self-closing is not a consideration at any point. ------------------------------------------------------------------------ [2015-05-15 15:05:51] cmb@php.net Related To: Bug #69641 ------------------------------------------------------------------------ [2015-05-06 21:38:22] cmb@php.net I've noticed that the respective changelog entry is also in error. FWIW: the behavioral change can be seen on <http://3v4l.org/W5aEu>. ------------------------------------------------------------------------ [2015-05-06 14:21:15] cmb@php.net Description: ------------ --- From manual page: http://www.php.net/function.strip-tags --- The third note about the $allowable_tags parameter reverts its meaning: | In PHP 5.3.4 and later, you will also need to include the | self-closing XHTML tag to strip these from str. For example, to | strip both <br> and <br/>, you should use: Instead of "strip", "preserved" or so should be used. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69584&edit=1
