Description:
------------
My concern is that PHP treats the handling of variable assignment inconsistently.  For example if I assign 01 to a variable $i01 the result will be an int 1, the same as if I had assigned 1 to the variable.  This works for values of 01,02,03,04,05,06, and 07.  However 08 and 09 are assigned as 0!

See repeatable test below.



Test script:
---------------
Assign variables:
	$s09 = '09';
	$c09 = (integer) '09';
           $i09 = 09;

Result of var_dump($s09.' / '.$c09.' / '.$i09);
    	string '09 / 9 / 0'

Assign variables:
	$s07 = '07';
	$c07 = (integer) '07';
           $i07 = 07;

Result of var_dump($s07.' / '.$c07.' / '.$i07);
    	string '07 / 7 / 7'

And when I just dump the $iXX variable I get:

	var_dump($i09);
Result	int 0

	var_dump($i07);
Result	int 7

This looks like a bug to me.
