This might is a newbie/stupid question. But, what does this operator below means? ->

Here are the warning message I am getting. Warning: mysqli_query() expects at least 2 parameters, 1 given in C:\wamp\www\sports\login.php on line 15 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in C:\wamp\www\sports\login.php on line 18 Notice: Undefined variable: r in C:\wamp\www\sports\login.php on line 43

Hello freaks, I can't seem to figure out why code not working correctly. Any advise greatly apprechiated. <?php include_once('connect/mysqlconnect.php'); $user = $_POST['uname']; $email = $_POST['email']; $pass1 = $_POST['pass1']; $pass2 = $_POST['pass2']; $checkname = mysqli_query("SELECT * FROM users WHERE uname='$user'"); if(isset($_POST['submitted'])){ if(mysqli_num_rows($checkname) > 0) { $errors[] = 'User name not available, please choose different name'; } else { $u = mysqli_real_escape_string($dbc, $user); } if(!empty($email)) { $e = mysqli_real_escape_string($dbc, $email); } else { $errors[] = 'You did not enter email address!'; } if($pass1 == $_POST['pass2']) { $p = mysqli_real_escape_string($dbc, trim($pass1)); } else{ $errors[] = 'Your password did not match. Please try again.'; } if(empty($errors)) { $insert = "INSERT INTO users(uname, email, pass1, register_date) VALUES ('$u','$e',sha1('$p'), NOW(register_date))"; // This execute above statement to INSERT into database $r = mysqli_query($dbc, $insert); } if($r) { //Print a message: echo '<h1>Thank you!</h1> <p>You are now registered.</p><p><br /></p>'; } else { echo ',<h1>Server Error</h1> <p>You could not be registered do to a server error. We apologize for any inconvience.</p>'; } } mysqli_close($dbc); ?>

The output I am looking for is: 5 random numbers from first array and 1 random number from second array in ascending order. Example: The winning numbers are 4,7,20,27, 31 and Mega number is 4.
