Simple MySQL Class connection Test

This is a very simple PHP class to check MySQL connection.Please read my other blog to create the MySQL table to make things work.

define("server","localhost");
define("conn_username", "root");
define("conn_password", "root");
define("database_name", "database_1.1");

require "database.inc.php";
 
 class mysql 
 { 
     function connect() { 
      @mysql_connect(server,conn_username,conn_password); 
      @mysql_select_db(database_name); 
  } 
 
     function query($query) { 
         $result = mysql_query($query); 
         if (!$result) { 
             echo 'Could not run query: ' . mysql_error(); 
             exit; 
   } 
   else{
    return $result;
   }
     } 
     
     function showresult($result) {
      $arr = array();
    @mysql_data_seek($result);
    while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {
     array_push($arr, $row);
    }
    return $arr;
     }
     function end() { 
         @mysql_close(); 
     } 
 }
 
 $mysql = new mysql(); 
 $mysql->connect(); 
       // $query = $mysql->query("SELECT * FROM Employee");
 print_r($mysql->showresult(/*$query)*/$mysql->query("SELECT * FROM Employee"))); 
 $mysql->end();
