Deny certain email (domian name)

[Anon]

Hi,

I'm new to PHP, I am about to launch a new website written in PHP, but I need some help on the form processing.

I have already restrict new registration from your a fake domain name (which I downloaded here), I wanted to added another function, which is to restrict free web base user from registering such as : email, mail and the like, anyone who can help.

Thanks,
Benedict

if I understood you right, you could do:

$restr_domains = array(
"hotmail.com",
"gmx.net",
"fake.uk"
);

// e.g. mail == [e-mail]
// domain is the second part of the mail address, split by "@".
$mailparts = explode("@", $mail);
$domain = $mailparts[1];

if(in_array($restr_domains, $domain))
{
echo "Sorry, we don't accept that domain.";
}
else
{
// process input ...
}

note that the restr_domains array could come from a file as well:
$restr_domains = file("restricted.txt");

in this case you must strip off the line delimiters of each entry:
for($i=0; $i<count($restr_domains); $i++)
$restr_domains[$i] = trim($restr_domains[$i]);

and now the in_array check would work.
