Are there any alternative methods or considerations to keep in mind when deleting files using PHP?

When deleting files using PHP, it is important to consider security implications and potential errors that may arise. One alternative method is to use the `unlink()` function along with `realpath()` to ensure the correct file path is being deleted. Additionally, you can check if the file exists before attempting to delete it to avoid errors. 

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

if (file_exists($file)) {
    if (unlink(realpath($file))) {
        echo 'File deleted successfully.';
    } else {
        echo 'Error deleting file.';
    }
} else {
    echo 'File does not exist.';
}
