报错：mysql_connect(): The mysql extension is deprecated and will beremoved in the future: use mysqli or PDO instead

解决方案：将mysql_xxx 换成mysqli_xxx

需要注意的问题

<?php
$link = mysql_connect('localhost', 'user', 'password');
mysql_select_db('dbname', $link);

改成mysqi
<?php
$link = mysqli_connect('localhost', 'user', 'password', 'dbname');

<?php
//  老的
mysql_query('CREATE TEMPORARY TABLE `table`', $link);
// 新的
mysqli_query($link, 'CREATE TEMPORARY TABLE `table`');
