How can I ensure that the XAMPP server is started before trying to access PHP files on localhost?

To ensure that the XAMPP server is started before trying to access PHP files on localhost, you can use a conditional check to verify if the server is running before attempting to access the files. This can be done by checking if the server is online using PHP's `file_get_contents()` function to make a request to `http://localhost` and verifying the response.

// Check if XAMPP server is running
if (file_get_contents('http://localhost') !== false) {
    // XAMPP server is running, proceed to access PHP files
    // Your code to access PHP files here
} else {
    // XAMPP server is not running, display an error message
    echo 'XAMPP server is not running. Please start the server before accessing PHP files.';
}
