How can server-side restrictions, like allow_url_fopen, affect the ability to read files generated by PHP scripts?

Server-side restrictions like allow_url_fopen can prevent PHP scripts from reading files generated by other PHP scripts or external URLs. To solve this issue, you can use the cURL library in PHP to make HTTP requests and retrieve the contents of files or URLs.

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com/file.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session and store the response
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Output the contents of the file
echo $response;
