checking mail and site 1

[mcvdmvs]

I am trying to check for valid email and url adresses with eregi, but i cant find out what to check: heres my code:

if(!eregi("([a-z0-9])*@([a-z0-9])*(\.[a-z0-9])*", $email))

theres one problem, does it match RFC standard? I tried finding answers on

http://www.rfc-editor.org.

I think i miss some characters, which are valid but are not matched in the above statement.

This is the url check:
if(!eregi("^http://[a-z0-9]*(\.[a-z0-9])*", $site))

It is also not complete.
please help... MiQ

echo "invalid email address";
}

else
echo "valid email address";

thanx, im gonna get the http stuff from RFC,
works deliciously, btw '+' in username has to be added:
(!eregi("^[0-9a-z]([-_.+]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,}$", $email))

Think we made it... ;-)

wat do the 2 backslashes do?

(!eregi("^[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,}$", $email))
