Concepts: empty () is to determine whether an array, variables, constants, string is empty.

empty () when the output true, description is empty, it is to have the opposite value is false.

<?php

$value1 = "";

$value2 = "666";

var_dump(empty($value1));  ::::true

var_dump(empty($value2));  ::::false
