WIN下apache+PHP配置PDO扩展问题

php.ini中:
extension_dir = "D:\php\ext\"
[PHP_CURL]
extension=php_curl.dll
;[PHP_GD2]
;extension=php_gd2.dll
[PHP_MYSQL]
extension=php_mysql.dll
;[PHP_MYSQLI]
;extension=php_mysqli.dll
[PHP_PDO]
extension=php_pdo.dll
;[PHP_PDO_FIREBIRD]
;extension=php_pdo_firebird.dll
[PHP_PDO_MYSQL]
extension=php_pdo_mysql.dll
===================================
运行时出现:
Fatal error: Class 'PDO' not found in F:\JetKing\pdo.class.php on line 25

pdo.class.php第25行代码:
$this->pdo = new PDO($this->dns,self::DBUser,self::DBPassWord);

php_pdo.dll 未加载成功.
php_pdo_mysql.dll 未加载成功
php_curl.dll 未加载成功


确认
与 pdo, mysql, curl 相关的DLL文件都COPY过去了吗?

最好是把 php 安装 包里, php.exe 所在文件夹里的DLL文件全部复制过去..

libmcrypt.dll
libhttpd.dll
libeay32.dll
libmhash.dll
libmysql.dll

ssleay32.dll
yaz.dll
