Description:
------------
At the top, it says: "(PHP 5 >= 5.1.3)".

However, in the Examples, it says, "Prior to PHP 5.1.4 this function can be simulated with:".

So which is it?  5.1.3 or 5.1.4?

According to the PHP 5 ChangeLog (and looking at the source), the correct answer is "5.1.3".


Expected result:
----------------
In Examples, it should say, "Prior to PHP 5.1.3 this function can be simulated with:".
