Description:
------------
If there are allowed tags, strip_tags will wrap around tags greater than 1023 (PHP_TAG_BUF_SIZE) characters.

If this is absolutely necessary it should at least be documented.

Also, why does strip_tags strip null bytes and why isn't this documented?

Reproduce code:
---------------
<?php
$str = "<a" . str_repeat(' ', 1021) . ">";
echo strip_tags($str, "<a>");


Expected result:
----------------
<a(1021 spaces)>

Actual result:
--------------
