mysql - The Correct Way To Load PHP's PDO Drivers? -

i start working pdo form database work , have ran problem, no pdo drivers loaded @ all.

i unzip php package "c:\php" , edit apaches httpd.conf file load php module so:

loadmodule php5_module "c:\php\php5apache2_2.dll" 

i edit php.ini file load mysql pdo driver module, uncommenting line:

extension=php_pdo_mysql.dll 

now create page calls phpinfo(); function, when page rendered, section under pdo empty, nothing has been loaded.

would know correct way configure apache , php mysql pdo driver loaded , useable?

before enabling php_pdo_mysql.dll extension should enable main pdo extension

extension=php_pdo.dll
