本文实例讲述了PHP提示 Deprecated: mysql_connect(): The mysql extension is deprecated的解决方法，在PHP程序开发中常会遇到这类问题。分享给大家供大家参考，具体的解决方法如下：

PDO:

    $dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass); 

MYSQLI:

    $link = mysqli_connect( 
     'localhost', /* The host to connect to 连接MySQL地址 */   
     'user',   /* The user to connect as 连接MySQL用户名 */   
     'password', /* The password to use 连接MySQL密码 */   
     'world');  /* The default database to query 连接数据库名称*/   

    if (!$link) { 
      printf("Can't connect to MySQL Server. Errorcode: %s ", mysqli_connect_error()); 
      exit; 
    }
