How can one handle authentication requirements when accessing files on a server from a PHP script, especially in cases where the server does not allow FTP connections?

To handle authentication requirements when accessing files on a server from a PHP script without FTP access, you can use HTTP authentication. This involves sending a username and password with each request to the server. You can set up the authentication headers in your PHP script to access the files securely. 

<?php
$username = 'your_username';
$password = 'your_password';
$url = 'http://example.com/file.txt';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");

$response = curl_exec($ch);

if($response === false){
    echo 'Error: ' . curl_error($ch);
} else {
    echo $response;
}

curl_close($ch);
?>
