I’m using Windows 7, wamp server version 2.2, PHP version 5.2.9. When I try to run my magento websites on a localhost it gives me the following error:

“The PDO extension is required for this adapter but the extension is not loaded”

I have double check that PDO extensions are enabled in the php.ini file. 

;extension=php_bz2.dll
extension=php_curl.dll
;extension=php_dba.dll
;extension=php_dbase.dll

    • First move the extension directory to \Windows\System32\inetsrv{php}\extension
    • Change the path from php.ini file

    I think you have a security problem to loading .dll! Try this and let me know the result.

    To find out which php.ini file has been loaded, try the following ( run in commandline and webserver to make sure which edition loading different environment).

    Checking the php.ini file path : 

    <?php
    $path = php_ini_loaded_file();
    echo 'The loaded file path is :' . $path;
?>
