What are potential methods to access a PHP file on a remote server from another server?

To access a PHP file on a remote server from another server, you can use cURL or file_get_contents functions in PHP. These functions allow you to make HTTP requests to the remote server and retrieve the contents of the PHP file.

// Using cURL to access a PHP file on a remote server
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/remote_file.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

echo $response;
```

```php
// Using file_get_contents to access a PHP file on a remote server
$url = 'http://example.com/remote_file.php';
$response = file_get_contents($url);

echo $response;
