What are common methods for integrating external scripts, such as news scripts, into a PHP website?

When integrating external scripts, such as news scripts, into a PHP website, one common method is to use PHP's `include` or `require` functions to bring in the external script file. This allows the PHP code in the external script to be executed within the context of the main PHP file. Additionally, you can use PHP cURL functions to fetch external scripts from a URL and then process the response accordingly.

// Method 1: Using include or require
include 'external_script.php';
// or
require 'external_script.php';

// Method 2: Using cURL to fetch external script
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/external_script.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

// Process the output as needed
echo $output;
