How can PHP beginners ensure they are using the correct functions to delete files on a server?

PHP beginners can ensure they are using the correct functions to delete files on a server by utilizing the `unlink()` function, which is specifically designed to delete files. It is important to provide the correct file path as an argument to `unlink()` to ensure the intended file is deleted. Additionally, beginners should always check if the file exists before attempting to delete it to avoid errors. 

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

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