创建pdo对象的代码:

<?php	try{		$dbh=new PDO("mysql:host=localhost;dbname=name","user","password");	}catch(PDOException $e){		echo 'Connection failed: '.$e->getMessage();	}?>
Copy after login


php.ini配置文件中都已经改成:
extension=php_mysql.dllextension=php_pdo.dllextension=php_pdo_mysql.dll
Copy after login



回复讨论(解决方案)

1、检查 php.ini 是否生效(你修改的文件位置是否正确)
2、php5.3 起已经没有了 php_pdo.dll(pdo 对象已经内置),如果 extension=php_pdo.dll 则会因加载失败而导致 pdo_mysql 失效
3、php5.2 及以前的 pdo 极不稳定,不建议使用

<?phpphpinfo();?>
Copy after login


看看有没有PDO。

使用的是php5.2,看来是由于稳定性的问题造成的,昨晚测试的不可以,今天早上创建成功了。
