The is_numeric functions works just fine. It returns trueor false based on whether the input variable is numeric or not. However, it is possible that unexpected results may occur when evaluating something like "34e6", which is a valid number (34,000,000). If you must know if a variable contains only digits 0-9, consider preg_match("/^\d+$/", $input) or similar.
