Subject: [PHP] Re: eregi problem
i'm not familliar with regular expresions but i think that ^a-z - means
that variable must start witx a-z characters
you can chek it here:
http://www.php.net/manual/en/reference.pcre.pattern.syntax.php
True, but look careful at what HE did:
if((eregi("[^a-zA-Z0-9]",$GP[sifre])
Putting the ^ _inside_ [] means NOT, so if any of the chars a-z0-9 is in the string itīs NOT matched.
actually, that's not entirely correct. The regexp basically means that
if there is any character in the string which is NOT alphanumeric, then
it is matched. So basically it returns true if there is a
non-alphanumeric char, and false otherwise. However, AFAIK the regexp
should be delimited, since if it isn't it behaves "differently"... I
just can't remember how differently it is exactly =/
Also thereīs no idea in having a-zA-Z in the pattern since eregi() is case
insensitive.
