How do you captured username?

<?



session_start();

session_start()

if (session_is_registered(username))


{

echo "[<a href=\"logout.php\">Logout</a>]";
echo "<br>";
$koneksi = mysql_connect("localhost", "davenet_davenet", "****") or die (mysql_error());
mysql_select_db("davenet_php", $koneksi);
$query = mysql_query("select status from anggota where username='syafii'", $koneksi);
$row = mysql_fetch_array($query);

if ($row["status"]=="1") // untuk mendapatkan
// status anggota
// 1 untuk admin /webmaster
// 0 untuk user biasa
echo "Anda webmaster";
else
echo "Anda member biasa";
echo "$row[status]";
echo "$username";
echo "$pass";
}
else // digunakan jika session tidak atau belum
// ter-register atas variabel username
header ("location:bukan_member.php");

?>


I wonder how do you captured username? Is it possible to print or (echo "") a registered username? how?

note: the result of echo "$username" above are empty.

Help is appreciated.

 

if(session_is_registered('username')){
echo $_SESSION['username'];
}

 

thanks. now it works.
