Hi patrilia,

Let´s say $input is the variable which is passed from the form:

1. Convert $input into an array!

$array_to_check=explode(".",$input); //see manual for details on explode()

2. Now asuming that we have a correct input $array_to_check[0] should be "www"

check it like:
if($array_to_check=="www"){ // do whatever you want here....
// you know the rest....

3. To check if the .com ending is there, check the last entry of $array_to_check:

$i=count($array_to_check);
if($array_to_check[$i]=="com"){ // do whatever you intend to do....

Hope that helped...
