use either is_numeric(), or for whole numbers only, use a regex:

preg_match('/^\d+$/', $test);

I'm tempted to say go read about ereg(), but since it's
just as long to provide a response...

return ereg( '^[[:alpha:]]*$', $testString );

 return ereg( '^[[:alpha:]]*$', $testString );

I should kick myself...

return ereg( '^[[:digit:]]*$', $testString );
