ID: 7472 Updated by: sniper@php.net Reported By: kjackson@gpu.srv.ualberta.ca -Status: Analyzed +Status: Verified Bug Type: Strings related Operating System: linux -PHP Version: 4.1.1 +PHP Version: 4.3.0-dev Previous Comments: ------------------------------------------------------------------------ [2002-01-22 07:54:43] yohgaki@php.net Version updated ------------------------------------------------------------------------ [2002-01-22 07:34:33] martin@humany.com Bug still exists in PHP 4.1.1, tested under Linux 2.4 and Windows XP with: echo strip_tags("first <?echo \"\\\"\"?> second"); ------------------------------------------------------------------------ [2001-02-10 15:14:36] jimw@php.net it is the unbalanced quotes that causes this. smaller example: <?php echo strip_tags("first <?echo \"\\\"\"?> second"); ?> refiling against 4.0, although it would be nice if any fix were backported. (or the behavior could be documented.) ------------------------------------------------------------------------ [2000-10-25 23:09:32] kjackson@gpu.srv.ualberta.ca oops, did not escape dollar signs. Doing so does not effect results. ------------------------------------------------------------------------ [2000-10-25 23:06:05] kjackson@gpu.srv.ualberta.ca This bug causes strip_tags to stop stripping php tags, if your string contains the following in a <?php?> delimiter. "title = \"([^\"]+)\"" Example: echo strip_tags(" aghh1 <?PHP if (eregi(\"title = \\\"([^\\\"]+)\", $x, $y)) echo \"foobar\"; ?> aghh2 "); will result in only aghh1 being reported when aghh2 should clearly be as well ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=7472&edit=1
