Summary: FILTER_VALIDATE_INT returns null for numbers with
leading zero(s)
Status: Not a bug

New Comment:
Don't use FILTER_VALIDATE_INT if you don't want to validate decimal notation
integers. Decimal notation integers do not have a leading 0, except for 0
itself,
of course. If you just want a filter that checks if the input is entirely made
of
digits, just use a regex. eg.
filter_var($string, FILTER_VALIDATE_REGEXP, ["options"=>["regexp"=>"/^[0-
9]+$/"]]);

FILTER_FLAG_ALLOW_OCTAL is not a feasible workaround for this issue.
echo filter_var('08', FILTER_VALIDATE_INT, FILTER_FLAG_ALLOW_OCTAL) ? "OKAY" :
"NOT OKAY";
// RESULT: "NOT OKAY"
FILTER_FLAG_ALLOW_OCTAL completely invalidates tests where the value has a
leading 0 and includes an 8 or 9.
