I did some more tests on this problem is that $str is still considered a
st
Yes, use preg_match("/^[0-9]{6}$/",$str) since it takes care of both
number and length.
You dont want to you is_numeric(), because that will match "4e5", etc..etc..

I'm pretty sure there will be a problem with using the is_int()
function. A similar problem was discussed a few weeks ago on this list
and is_int() will return true for a "number" like 1000e2. The "e" being
treated as an exponential representation of an integer.
It might be more reliable to add

If you care about performance at all, try and find away around the
problem without regular expressions...
I tested
if( (strlen($str) == 6) && (is_int($str)) )
vs
if(ereg('^[0-9]{6}$',$str))
...on my LAN test server with 10 iterations, and the regexp was
nearly 2 times slower than the f
if(!ereg('^[0-9]{6}$',$string) die('not six numbers');
you might want to trim off white space first.
