创建pdo对象时出现Connection failed: could not find driver
创建pdo对象的代码：

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

Copy after login

php.ini配置文件中都已经改成：

<br />extension=php_mysql.dll<br />extension=php_pdo.dll<br />extension=php_pdo_mysql.dll<br />

Copy after login

------解决思路----------------------
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
------解决思路----------------------

<br /><?php<br />phpinfo();<br />?><br />

Copy after login

看看有没有PDO。
