Bug description:intval doesn't throw warning when value is bigger than the
maximum allowed
Description:
------------
If you use intval with an argument that is bigger than 2147483647 the
result will always be 2147483647.
That's a problem that PHP doesn't throw an Error or Warning, because at the
first glance, it looks like a mistery from where comes this magic number ?
If someone used intval with an argument that is bigger than 2147483647 IMHO
php should die with some message like this:
'Warning: Argument too big for intval. Maximum allowed is 2147483647'
or
'Error: Argument too big for intval. Maximum allowed is 2147483647'
I lost almost one hour to discover from where the magic number came... If
there was the Error or Warning, it would be MUCH EASIER to solve the
problem.
Test script:
---------------
<?php
echo intval('11111111111'); ?>
Expected result:
----------------
Throwing an Error (die) or Warning showing that the argument passed for
intval was TOO BIG.
Actual result:
--------------
The function does NOT give any type of hint of the problem, and returns a
fixed value 2147483647 as result, DOES NOT MATTER what the argument is, as
long as it is bigger than 2147483647...
