<?php     // player 1 login information $p1name = $_post['p1name']; $p1pass = $_post['p1pass'];  // player 1 login information $p2name = $_post['p2name']; $p2pass = $_post['p2pass'];  // check user information $player1 = get_user($p1name, $p1pass); $player2 = get_user($p2name, $p2pass);  // has user been found? $found = array(  'player1' => false,   'player2' => false );  // check if use information matches if($player1['username'] == $p1name && $player1['password'] == $p1pass) {  $found['player1'] = true; } if($player2['username'] == $p2name && $player2['password'] == $p2pass) {  $found['player2'] = true; }  function connect($db_host, $db_name, $db_pass, $db_table) {     $connection = mysql_connect($db_host, $db_name, $db_pass);      mysql_select_db($db_table, $connection);  }  function get_user($username, $password) {  $query = 'select * users';  $query .= ' username = ' . mysql_real_escape_string($username);  $query .= ' , password = ' . mysql_real_escape_string(sha1($password));  $result = mysql_query($query);  return mysql_fetch_assoc($result); }

you needed create instances of returned user information check each players against own.
