Part 2: Verifying Your Installation

Once you have installed VSCode, XAMPP, and necessary extensions, it’s important to verify that everything is set up correctly. This part of the tutorial will guide you on how to check your PHP installation and ensure that MySQL is running properly.

Verifying PHP Installation

To confirm that PHP is installed and accessible:

  1. Check PHP Version:
    • Open a command prompt (Windows) or terminal (macOS).
    • Type the following command and press Enter: php -v
    • This command should display the PHP version installed on your system. Ensure it matches the version you expect (as provided by XAMPP).
  2. Create a PHP Info File:
    • Open VSCode and create a new file named info.php.
    • Type the following PHP code: <?php phpinfo(); ?>
    • Save this file in the htdocs directory of your XAMPP installation.
    • Open a web browser and navigate to http://localhost/info.php.
    • You should see a web page displaying all current settings and configurations of PHP. This indicates that PHP is running correctly through your Apache server.

Verifying MySQL Connection

It’s also essential to confirm that MySQL is running and you can connect to it:

  1. Check MySQL Service:
    • Open the XAMPP Control Panel.
    • Ensure that the MySQL service is started. If it’s not, click on the Start button next to MySQL.
  2. Connect to MySQL via Command Line:
    • Open a command prompt (Windows) or terminal (macOS).
    • Connect to MySQL by typing: mysql -u root -p
    • Press Enter (by default, XAMPP MySQL has no password for the root user).
    • If you see a MySQL command prompt, it means you are connected to the MySQL server.
