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

RE: [PHP] ereg checking if its only numbers
With ereg it could be:
if(ereg(^[^[:digit:]]+$))
echo 'something else came through';
Untested though ...

Re: [PHP] ereg checking if its only numbers
try:
?
if(ereg([0-9]{9}, $string)){
echo Success, 9 numbers!;
} else {
echo Failure, not 9 numbers.;
}
?
There is a great book on regular expressions by o'reily.
