PDO串連MySQL出錯解決方案

PDO串連MySQL出錯

$dbms = 'mysql';
$dbName = 'db_mrbook';
$user = 'root';
$pwd = '111';
$host = 'localhost';
$dsn = "$dbms:host = $host;dbname = $dbName";
try{
$pdo = new PDO($dsn,$user,$pwd);
echo "PDO連結資料庫成功";
}catch(Exception $e){
echo $e->getMessage()."
";
}
?>
運行時顯示could not find driver
修改了php.ini.dist和php.ini.recommended中的擴充，去掉了extension=php_mysql.dll、extension=php_pdo.dll和extension=php_pdo_mysql.dll前面的分號，重啟了Apache，還是同樣的錯誤，請大大幫幫忙阿

------解決方案--------------------
phpinfo() 看看是否載入成功
------解決方案--------------------
看看phpinfo()中的load configure file ，看看載入的是那個php.ini檔案
------解決方案--------------------
這樣就可以了

PHP code

PDOPDO support enabled PDO drivers  mysql, odbc, sqlite  pdo_mysqlPDO Driver for MySQL enabled Client API version  mysqlnd 5.0.8-dev - 20102224 - $Revision: 308673 $  PDO_ODBCPDO Driver for ODBC (Win32) enabled ODBC Connection Pooling  Enabled, strict matching  pdo_sqlitePDO Driver for SQLite 3.x enabled SQLite Library  3.7.4

你改的php.ini 是否是 Loaded Configuration File 對應的php.ini
