Description:
------------
The Documentation for strip_tags() should mention that the function does not actually look for any html or php Tags but actually just searches for the "<" sign and removes everything from that Position  until it encounters a ">" sign. If there is no ">" in the String the whole string will be cut from the Position of the "<" sign.

Reproduce code:
---------------
---
From manual page: function.strip-tags
---
<?php
$text = "This text has no HTML or PHP Tags and is <50 characters in total length but it wont be listed!";
echo strip_tags($text) . '<br/>';
$text = "This Text <span>Text has HTML Tags</span> and will be listed correctly.";
echo strip_tags($text);
?>

Expected result:
----------------
Both Text Variables to be returned completely with the exception of the <span> and </span> which are html tags. But thats another issue which I doubt will be fixed. So the Added Note in the Documentation should suffice.

Actual result:
--------------
This text has no HTML or PHP Tags and is 
This Text Text has HTML Tags and will be listed correctly.
