http://www.php.net/is_numeric
is the function you are looking for. No need for fancy regexps.
The OP is looking for an integer, but is_numeric() will return true for float values and also for numbers in scientific notation. So "12.3" and "12E3" will be TRUE.
The original $number != intval($number) should work for detecting bad input.
