What potential issues can arise when trying to download a zip file using PHP headers?

When trying to download a zip file using PHP headers, potential issues can arise if the file is not properly handled or if there are errors in the headers being sent. To solve this, ensure that the file path is correct, set the appropriate headers for file download, and use readfile() function to output the file contents. 

$file = 'path/to/your/file.zip';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/zip');
    header('Content-Disposition: attachment; filename=' . basename($file));
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
} else {
    echo 'File not found';
}
