Laravel PDOException: How to Fix 'could not find driver' on Servers with Limited Access?

Laravel: Resolving "PDOException: could not find driver" Exception

When developing Laravel applications with limited access, such as on servers where only MySQL and FTP are available, database connectivity issues can arise. One common exception encountered is "PDOException: could not find driver."

This exception typically occurs when the appropriate PDO driver is not loaded or enabled in your PHP installation. To resolve this problem, you need to ensure that the necessary extension is both installed and enabled.

Specifically, for MySQL connectivity, you need to verify that the "pdo_mysql" extension is loaded. To do this, check your php.ini file for the following line:

;extension=pdo_mysql.so

If the line is commented out (preceded by a semicolon), uncomment it and save the file. This will enable the "pdo_mysql" extension.

In your specific case, you mentioned that you have access to Apache extensions. According to the list of extensions you provided, it appears that you have the "20-pdo_mysql.ini" extension installed. This suggests that the "pdo_mysql" extension is available.

However, if uncommenting the "pdo_mysql.so" line in your php.ini file does not resolve the issue, you may need to restart your Apache web server for the changes to take effect. To do this, depending on your server configuration, you can run the following commands:

service apache2 restart
sudo systemctl restart apache2

After restarting your web server, try running your Laravel command again (php artisan migrate:refresh --seed). You should no longer encounter the "PDOException: could not find driver" exception.
