PDOException，在PHP7上找不到驱动程序

Question

I'm using Slim framework and I got a PDO error. I just installed xamp on mac and I'm using PHP Version 7.

Type: PDOException
Message: could not find driver
File: /Applications/XAMPP/xamppfiles/htdocs/app/index.php

I checked my phpinfo and I have pdo_mysql enabled.

On a windows server you can add or uncomment the following lines in your php.ini

extension=php_pdo.dll
extension=php_pdo_mysql.dll

OR:

extension=pdo.dll
extension=pdo_mysql.dll

UPDATED:

For example code:

            'db'=>array(
                    'connectionString' => 'mysql:host=localhost;dbname=yii_trackstar',
                    'emulatePrepare' => true,
                    'username' => 'yii',
                    'password' => '######',
                    'charset' => 'utf8',
            ),

Replace localhost by 127.0.0.1

before restart your XAMPP.
