[PHP-WIN] What does an @ sign before a VARIABLE do?

[Mike Flynn]

Hey all,

In the PHOBUILDER tutorial on sessions the sample code has a @ sign before 
some of the variable names.. like:
if (@$userid && @$password) {
   $res = @mysql_query("SELECT userid FROM users WHERE userid='$userid' AND 
password='$password'");
   if(@mysql_num_rows($res) != 0) {
     $verified_user = $userid;
     session_register("verified_user");
   }
}
I've never seen that before and am curious what it does.  I've seen it 
before function calls, but never before variables.

Thanks!
-Mike
