解决Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in,pdomysqli
php 5个版本,5.2、5.3、5.4、5.5,怕跟不上时代,新的服务器直接上5.5,但是程序出现如下错误:
Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in,
看意思就很明了,说mysql_connect这个模块将在未来弃用,请你使用mysqli或者PDO来替代。

解决方法1:
禁止php报错
1 2 3 | display_errors = On改为display_errors = Off |
鉴于这个服务器都是给用户用的,有时候他们需要报错(...都是给朋友用的,^_^),不能这做,让他们改程序吧,看方案2.
解决方法2:
常用的php语法连接mysql如下
1 2 3 4 5 6 7 | <?php$link = mysql_connect('localhost', 'user', 'password');mysql_select_db('dbname', $link); 改成mysqi<?php$link = mysqli_connect('localhost', 'user', 'password', 'dbname'); |
常用mysql建表SQL如下
1 2 3 4 5 | <?php// 老的mysql_query('CREATE TEMPORARY TABLE `table`', $link);// 新的mysqli_query($link, 'CREATE TEMPORARY TABLE `table`'); |
解决方法三:
在php程序代码里面设置报警级别
1 2 | <?phperror_reporting(E_ALL ^ E_DEPRECATED); |
Deprecated的问题就这样解决掉了,不过还是建议大家尽快取消mysql的用法,全部都走向mysqli或者mysqlnd等等。mysql确实是太不安全而且太老旧了。
