Why Can't Laravel Find My MySQL Driver Despite Having PDO and MySQL Extensions Installed?

PDO Exception: Could Not Find Driver in Laravel

Encountering a "could not find driver" exception while using Laravel and PHP can be frustrating. This issue arises when the required PDO driver is not available within the PHP environment. It can occur in various scenarios, such as when working on a limited-access server or when the appropriate extensions are not loaded.

As mentioned in your query, you have access to MySQL and FTP on your server and are experiencing this exception while migrating your database. The installed Apache extensions on your server include both MySQL and PDO, which should be sufficient for Laravel to function properly.

Resolving the Issue

To resolve this issue, you can try the following steps:

1. Enable the pdo_mysql Extension: Ensure that the pdo_mysql extension is enabled in your PHP configuration file (php.ini). This extension is required for Laravel to communicate with MySQL. If it is not enabled, uncomment the following line in your php.ini file:

;extension=pdo_mysql.so

2. Restart Your Web Server: After making changes to your php.ini file, restart your web server. This action is necessary for the changes to take effect. Restarting the server will load the updated php.ini configuration.
3. Clear Laravel Cache: Once the web server has been restarted, clear the Laravel cache to ensure it does not contain any outdated information. You can do this by running the following command:

php artisan cache:clear

4. Check Your Database Connection: Verify that Laravel can connect to your MySQL database properly. Open your .env file and ensure that your database credentials (e.g., host, username, password, database name) are correct.
5. Double-Check Installed Extensions: If the previous steps do not resolve the issue, double-check the installed Apache extensions on your server. Ensure that the pdo extension is enabled, and any other necessary extensions, such as mbstring, are also present.

If the above methods do not resolve the issue, you may need to investigate further, considering factors such as PHP version compatibility and any potential configuration issues within your hosting environment or Laravel installation.
