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 100000 iterations, and the regexp was nearly 2 times slower than the first solution. IMHO, it's also faster to read and modify the first solution too -- especially for those with minimal regexp experience.

I would like to know how to verify that there are 6 numbers (only numbers in a field) that will be submitted to a database? Any clues!
