How can PHP scripts be utilized to deliver files with cryptic URLs?

To deliver files with cryptic URLs using PHP scripts, you can generate a unique token for each file and map it to the actual file path on the server. When a user requests a file with the cryptic URL, the script looks up the token in a database or mapping array to find the corresponding file path and serves the file to the user. 

<?php
// Generate a unique token for the file
$token = bin2hex(random_bytes(16));

// Map the token to the file path in a database or array
$tokenMap = [
    $token => '/path/to/your/file.txt'
];

// Serve the file when a user requests it with the cryptic URL
if(isset($_GET['token']) && isset($tokenMap[$_GET['token']])) {
    $filePath = $tokenMap[$_GET['token']];
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($filePath).'"');
    readfile($filePath);
} else {
    echo 'File not found.';
}
?>
