What is the recommended method in PHP to delete files from a server?

When deleting files from a server in PHP, it is recommended to use the `unlink()` function. This function takes the file path as an argument and deletes the specified file from the server. It is important to ensure that the file path is correct and that the file has the necessary permissions to be deleted. 

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

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