Bug #42213 Weird integer conversion behaviour

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:
$a = intval(08);
$b = intval('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 and the instructions on how to report
a bug at

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