[email protected] ("php-bugs at aspectis dot net")
| Newsgroups | php.bugs |

| Message-ID | <[email protected]> |
From: php-bugs at aspectis dot net
Operating system:
PHP version: 7.1.3
Package: *General Issues
Bug Type: Bug
Bug description:strip_tags altering attributes
Description:
------------
The manual claims that strip_tags "does not modify any attributes on the
tags that you allow" (http://www.php.net/function.strip-tags), which
unfortunately isn't quite true:
The characters "<" and ">" get stripped from all attribute values.
All versions at least from 5.4 seem to be affected.
Test script:
---------------
echo strip_tags('<img src="example.jpg" alt=":> :<">', '<img>');
Expected result:
----------------
<img src="example.jpg" alt=":> :<">
Actual result:
--------------
<img src="example.jpg" alt=": :">
