Check if a string ends with an item in an array

So I am looping over a massive array of user accounts.

I am getting the UserAccount email as $email

I need to check if the value after the last '.' matches my array of valid TLDs. So if my email is john.weland@example.com, find the last "." and compare it to a array of valid TLDs in this case COM is in that list. so it should be valid.

However john.weland@example.coma, coma is not in that array thus it should be invalid.

I made this list of TLDs in to an array.

I think this is what you want: http://php.net/manual/en/function.strrchr.php. I trust you can write the comparison script.
