我有来自easyui http://www.jeasyui.com/tutorial/app/crud.php的这个用户表文件php，但我不知道如何连接到MySQL

和这个MySQL数据库
CREATE TABLE `users` (
`id` int(11) NOT NULL auto_increment,
`firstname` varchar(50) default NULL,
`lastname` varchar(50) default NULL,
`phone` varchar(200) default NULL,
`email` varchar(200) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
答案 0 :(得分：0)
很高兴它没有连接。不推荐使用mysql_*函数，因为它们已被弃用。切换到PDO。
像这样重写你的连接。
try
{
$dbh = new PDO("mysql:host=localhost;dbname=$dbname",$dbuser,$dbpass);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e)
{
echo 'Connection failed: ' . $e->getMessage();
}
