From: email at steffenweber dot net Operating system: Linux PHP version: 5.2.1 PHP Bug Type: Strings related Bug description: strip_tags does not handle single quotes correctly (regression) Description: ------------ The fix for bug #40432 (http://bugs.php.net/bug.php?id=40432) seems to have broken the strip_tags function. I'm using PHP 5.2.1 and have additionally applied this patch: http://cvs.php.net/viewvc.cgi/php-src/ext/standard/string.c?r1=1.445.2.14.2.39&r2=1.445.2.14.2.40&view=patch Reproduce code: --------------- <?php $html = '<span title="Bug \' Trigger">Text</span>'; var_dump(strip_tags($html)); ?> Expected result: ---------------- Prints "Text". Actual result: -------------- Prints the empty string. Notice that the following slightly modified code correctly prints "Text": <?php $html = '<span title="Foo">Text</span>'; var_dump(strip_tags($html)); ?> -- Edit bug report at http://bugs.php.net/?id=40637&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40637&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40637&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40637&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40637&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40637&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40637&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40637&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40637&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40637&r=support Expected behavior: http://bugs.php.net/fix.php?id=40637&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40637&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40637&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40637&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40637&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40637&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40637&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40637&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40637&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40637&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40637&r=mysqlcfg
