#40637 [NEW]: strip_tags does not handle single quotes correctly (regression)

[email at steffenweber dot net]

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 ([url]http://bugs.php.net/bug.php?id=40432[/url]) seems to
have broken the strip_tags function.

I'm using PHP 5.2.1 and have additionally applied this patch:
[url]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&vie w=patch[/url]

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));
?>
