PHP提示Deprecated: mysql_connect(): The mysql extension is deprecated的解决方法

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：

将下面代码改为mysqli或pdo即可。

function connectit () { 
global $cfg; 
mysql_connect($cfg['db_host'], $cfg['db_user'], $cfg['db_pass']) or die(mysql_error()); 
mysql_select_db($cfg['db_name']); 
} 

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; 
}

希望本文所述对大家的php程序设计有所帮助。
