I have a value from $_GET, and I want it to be integer.
$val = "123";
is_integer($val); // false
is_numeric($val); // true
How do I check if it's of type int?
Do I really have to use regex, or multiply it by 1 and try is_integer then?

lol that was fast. It didn't show in the suggested questions though. – MightyPork Jul 09 '14 at 13:09

try http://www.php.net/manual/en/function.is-numeric.php – Rakesh Sharma Jul 09 '14 at 13:12

@RakeshSharma no good, that will give me also floats. but `(string)(int)$val == $val` works good for me. – MightyPork Jul 09 '14 at 13:19

[`ctype_digit`](http://php.net/ctype_digit) – deceze Jul 09 '14 at 13:20

giving you true cause Finds whether a variable is a number or a numeric string (so your $val is a string but having numeric chars) – Rakesh Sharma Jul 09 '14 at 13:20

@deceze `ctype_digit` is useless, I want also negative integer value. – MightyPork Jul 09 '14 at 13:32
