Description:
------------
When placing a zero in front of a number PHP will convert it automatically to an integer value, but it becomes a zero rather than the number after the zero.

Reproduce code:
---------------
<?php
$a = intval(08);
$b = intval('08');
var_dump($a,$b,08);
?>


Expected result:
----------------
int(8) int(8) int(8)

Actual result:
--------------
int(0) int(8) int(0)

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Numbers starting with a 0 are octal numbers and there is no such thing as "8" there.
