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

ID: 14623 User updated by: jeroen@zwolnet.com Reported By: jeroen@zwolnet.com Status: Open Bug Type: Strings related Operating System: linux PHP Version: 4.0.6 Old Assigned To: elixer Assigned To: New Comment: The code example shows the problem on my PHP 4.0.6 (redhat distr) - if you add the 110 lines print_r() shows an empty array, if you delete half of it the headerinfo is there. Yes it is a memory eater, but the only purpose was to have a reproducable and simple example ... next time I will make a usefull example - telling jokes or something :). If you look in the C source - is the whole file been read? Can the # of bytes read be os/config (default blocksize)dependent? Have you tried it with more memory eating xxx's? Or it might be solved in 4.1.0 (CVS)? Jeroen Previous Comments: ------------------------------------------------------------------------ [2001-12-21 19:15:52] elixer@php.net 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 ------------------------------------------------------------------------ [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.
