mysql_pconnect() difference with the "@"

what is the difference betweeen :

1) @ $db = mysql_pconnect("localhost", "userid", "passwd");

and

2) $db = mysql_pconnect("localhost", "userid", "passwd");

The @ symbol suppresses errors for the function you use it with.

It mysteriously contacts the pentagon and lets them know all illegal software running on your PC. Don't ever use it!
