In what scenarios would using the "unlink" function in PHP be preferable over other file deletion methods?

The "unlink" function in PHP is preferable over other file deletion methods when you want to directly delete a file without any additional steps or checks. It is a simple and straightforward way to remove a file from the filesystem. 

$file_path = "path/to/file.txt";

if (file_exists($file_path)) {
    unlink($file_path);
    echo "File deleted successfully.";
} else {
    echo "File does not exist.";
}
