is_integer probably wouldn't work, since you're dealing with strings here.
Your best friend here would probably be 'is_numeric' which would return true
on both the string '1' as the integer 1 true. As well as 1.1 and '1.1'. The
only one solution I could think if would be:
preg_match('/^\d+$/', $stnr);

Ain't it always the small things like this that consume too much time?
