How can I check to see if a string var holds a number? Is regex the only way to do this? For example I have code where the var could hold "10" or "ten". If the string is a number, do one thing, if it isn't do something else. is_int doesn't work, intval converts "ten" to a number so that doesn't work....is_numeric http://ca.php.net/is_numeric - Ben
