New Comment:
The issue is that --($a ** 2) is not a valid expression. Thus the parser parses it the only possible
way: (--$a) ** 2.
And the manual is therefore still correct.

Description:
------------
On page http://php.net/manual/en/language.operators.precedence.php
indicates that the operator ** is of higher priority than ++ -- ~ (int) (float) (string) (array)
(object ) (bool) @, but it is not.
Test script:
---------------
// this script returns 9 instead of 15
$a=4;
echo --$a**2;
