Are there alternative methods to unlink a file in PHP that may avoid permission errors?

When trying to unlink a file in PHP, permission errors may occur if the file is not writable or if the PHP process does not have the necessary permissions to delete the file. One alternative method to avoid permission errors is to use the `unlink()` function within a try-catch block and handle any potential exceptions that may arise. 

try {
    if (file_exists($file_path)) {
        unlink($file_path);
        echo "File successfully unlinked.";
    } else {
        echo "File does not exist.";
    }
} catch (Exception $e) {
    echo "Error unlinking file: " . $e->getMessage();
}
