try: if (eregi("^[a-zA-Z0-9]*$", $name))
This searches for [a-zA-Z0-9] between start and end of line with no other
intervening characters

Subject: [PHP] newbie: regular expression suggestios
Hi,
I am using (getting to grips with) regular expressions for validating
form data and have come across a little problem:
I have a statement like the following:
if (eregi("^[a-z0-9]{strlen($name)}$, $name))
{
blah...
return true;
}
, but the strlen($name) does not seem to evaluated. Is there any way
this can be accomplished? If the code above is not clear (or correct!),
I am returning true iff the input is comprised of chars
(letters/numbers) only. Maybe there's a better/more efficient way to
accomplish this..?
Any information greatly aprpeciated. Thanks in advance!
- Best regards,
Lee Reilly
