How can a PHP developer handle server configurations that restrict file access to remote servers when attempting to retrieve content from external websites?

When server configurations restrict file access to remote servers, a PHP developer can use cURL to retrieve content from external websites. cURL allows PHP to make HTTP requests to external servers, bypassing the restrictions on file access.

php 
$url = 'https://www.example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output;
