Subject: [PHP] ereg checking if its only numbers
Ive been playing around with ereg for about half an hour and having no joy
because I dont really understand the medhod behind it and how it all works.
But what im trying to do is check to see if a 9 digit string is all numbers
and nothing else
$string1 = "123456789"
$string2 = "123456abc"
how would I check either string with an IF statement and make it continue
on string 1 (ie, all numbers) and error on string 2 (not all numbers).
Any suggestions ?
Thanks
Chris
