[RESOLVED] Numeric field?

[nogeekyet]

I am simply want to know if a field/string is numeric. I don't care how big the number is. I want to make sure the field does not contains any letters or special characters. I can't find a simple function to do that with. Is there something like: if (numeric) {do something}?

is_numeric($var);
