Basic String Question

[Anon]

Newbie string question.

What's the best way to check if the incoming variable stored in
getenv("SERVER_NAME")
contains a given string?

We have 3 domians www.domain.com, www.domain2.com and www.domain3.com. I want to check for the presence of domain2 or domain3 in the SERVER_NAME variable and redirect these to domain.com.

I'm planning on using strtolower(); to make sure the comparison is done all in lower case, but I'm not sure how to get around the problem of sometimes the www will be present, other times it won't.

Any help would be greatly appreciated as our ISP appears incapable of doing this trivial task with Virtualhost in Apache.

i would use if statements in conjunction with header

<?php

if(eregi("domain2.com", $SERVER_NAME)){
header ("Location: http://www.domain.com");
exit;
}elseif(eregi("domain3.com", $SERVER_NAME)){
header ("Location: http://www.domain.com");
exit;
}
?>

using eregi checks $SERVER_NAME for the string 'domainX.com' (case insensitive; use just ereg if you want case sensitivity). if it finds 'domainX.com', it reroutes the user directly to www.domain.com.

the www part is insignificant. this will work whether it's there or not.
