Verifica daca exista utilizatorul

Submitted by merlin on Mon, 07/24/2006 - 12:55.

Am un script PHP care inregistreaza utilizatori in mySQL. Tabela se numeste register. Cum pot verifica daca utilizatorul exista deja in baza de date?

Mersi :)

Submitted by admin on Mon, 07/24/2006 - 13:01.

$users = mysql_query("SELECT username FROM register WHERE username='".$_POST['username']."'");
$result = mysql_num_rows($users);

if ($result == 0) {
  print "Utilizatorul este inregistrat";
} else {
  print "Utilizatorul exista in db";
}

Bafta ;)
