Summary: Wrong implicit conversion of strings containing
hexadecimal numbers to int
Status: Open
Type: Bug
Package: Scripting Engine problem
Operating System: Linux 2.6.32 Ubuntu 10.04/i686
PHP Version: 5.3.3

New Comment:
IMO the behavior of the implicit type juggling is correct,
and the result of the explicit type cast is erroneous in this regard.
Anyway, both results should match.

Description:
------------
If string contains hexadecimal number, such as '0x05' it correctly explicitly
casts to integer(resulting zero):
php > var_dump((int) '0x05');
int(0)
but incorrectly casts implicitly (resulting its value, 5)
php > var_dump(1 * '0x05');
int(5)
Same for floats:
php > var_dump((float) '0xffffffffff');
float(0)
php > var_dump(1 * '0xffffffffff');
float(1099511627775)
P.S.: Tests were made on x86 (i686) Linux machine.
Test script:
---------------
<?php
var_dump(1 * '0x05');
var_dump(1 * '0xffffffffff');
Expected result:
----------------
int(0)
float(0)
Actual result:
--------------
int(5)
float(1099511627775)
