Bug #14623 Updated: get_meta_tags only looks in begin of file

ID: 14623 Updated by: elixer Reported By: jeroen@zwolnet.com Status: Open Bug Type: Strings related Operating System: linux PHP Version: 4.0.6 Assigned To: elixer New Comment: That example works fine here from the local CVS. I don't think it has anything to do with PHP code being at the top of the page. My wager is that you have _useful_ code that is breaking get_meta_tags, my guess is that the code contains the string "</head" in it somewhere. Does this example piece of code actually not work on your setup? All it seems to do is waste memory :) Sean Previous Comments: ------------------------------------------------------------------------ [2001-12-21 05:48:23] jeroen@zwolnet.com The way I use it is quite different: When a file is parsed it is 'wrapped': a prepended wrapper opens the file and layouts it. Based on the meta tags a layout is choosen, menus added, header defined, etc. This way the content exists out of plain HTML files that are build into the vieuwed pages when parsed. (That can differ for showing, printing, spiders, ... all with the same content - that is easy to maintain even by dummies :).)

I think it's makes way more sense to use g_m_t on a parsed file.

The only time I am seeing this fail is if the text "</head" appears in the "working code" that you mention. Sean ------------------------------------------------------------------------ [2001-12-20 10:59:01] jeroen@zwolnet.com get_meta_tags() seems to look only in the beginning of a file, meaning that e.g. if there is a lot of PHP code before the HTML header it will return nothing ... Tested using get_meta_tags() on local files with about 9000 characters of PHP code before HTML HEADER. Might be by design (speed), but then a warning is needed in doc: when adding working code, things (get_meta_tags()) stop working ... Workaround: if possible move code after header or if not include a file :( ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14623&edit=1
