What are the best practices for handling external scripts like the MT Counter in PHP?

When handling external scripts like the MT Counter in PHP, it's best practice to use the `file_get_contents()` function to retrieve the script content and then evaluate it using `eval()` function. This allows you to execute the external script within your PHP code while ensuring security by not directly including the script.

// Retrieve external script content
$external_script = file_get_contents('http://example.com/mt_counter.php');

// Evaluate the external script content
eval($external_script);
