PDO: could not find driver

  • | 282 points

    Hello, I just tried with PDO to connect to the database and habe the "could not find driver" error.
    I made following checks: php.ini has the correct dll uncommented, extension_dir is in .ini correct.
    If I give a wrong database name: SQLSTATE[42000] [1049] Unknown database
    If I give a wrong user name: SQLSTATE[28000] [1045] Access denied for user
    If I give a wrong password: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)
    If the 3 values (db, user and password) are OK (meaning that I can connect to the db, right?), "could not find driver" error is displayed.

    With this code
    if (!defined('PDO::ATTR_DRIVER_NAME')) {
    echo 'PDO is unavailable<br/>';
    elseif (defined('PDO::ATTR_DRIVER_NAME')) {
    echo 'PDO is available<br/>';

    my output is

    PDO is available
    Array ( [0] => mysql ) .

    So what am I doing wrong/ why do I have the "could not find driver" error?

    @tcheulboulet : Did you enable the php_pdo_mysql.dll extension also?

    The last printscreen seems to say that this extension is enabled...

    @tcheulboulet : Yes, I see you enabled them. So, it is not because of your settings. You can check this: https://stackoverflow.com/questions/42848062/php-could-not-find-driver-pdo-mysql
