Description:
------------
sometimes php doesn't seem to consider zeros in front of an integer, (like 01 == 1, 02 == 2) but sometimes the results are unexpected.

Reproduce code:
---------------
$numbers = array(01,02,03,04,05,06,07,08,09,10,001,002,003,004,005,006,007,008,009,010, 011, 012, 013, 014, 015, 016, 017, 018, 019, 020, 0001, 0002, 0003, 0004, 0005, 0006, 0007, 0008, 0009, 00010);
foreach($numbers as $number) print $number.",";

Expected result:
----------------
1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15, 16,17,18,19,20,1,2,3,4,5,6,7,8,9,10,

Actual result:
--------------
1,2,3,4,5,6,7,0,0,10,1,2,3,4,5,6,7,0,0,8,9,10,11,12,13,14,15,1,1,16,1,2,3,4,5,6,7,0,0,8,

http://www.php.net/manual/ and the instructions on how to report

Congratulations, you have discovered the notation for handling octal numbers ;-)
