hi Heba
try this out

PHP

$DSN ="localhost " // hostname
$User="root"    // the username
$Password="password" // your password come in the 
$ conx = mysqli_connect($DSN,$User,$Password); 

// check if connection works

if (mysqli_connect errno())
{
   echo "failed to connect to mysql".mysqli_connect_errno();
}else
  echo "connected :)" ;

?>
