Summary: intval doesn't throw warning when value is bigger
than the maximum allowed
Status: Bogus
Type: Bug
Package: *General Issues
Operating System: all

So I suggest to change the behaviour. In my opinion, throwing a Warning
would be more intelligent than returning 2^31-1. It is an Error because
it offends Mathematics. A function with different arguments, in this
case should return different results, BUT UP TO NOW, it may return
always 2^31-1. Can't anyone else see this ? The way it is today turns
PHP into a "hiden bugs" language.

No, it doesn't. This is expected and documented behaviour.

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...
