What is the best practice for automatically deleting a file after it has been downloaded using PHP?

When a file is downloaded using PHP, it is important to ensure that the file is deleted after the download process is complete to prevent unauthorized access or misuse of the file. One way to achieve this is by using the unlink() function in PHP to delete the file after it has been successfully downloaded. 

// Download file code here

$file_path = 'path/to/your/file.txt';

// Download file code here

// Delete the file after download
if (file_exists($file_path)) {
    unlink($file_path);
}
