The PHP language provides several comparison operators that allow us to compare two different values, resulting in either true or false:
==: equal===: identical!=: not equal<>: not equal!==: not identical<: less than>: greater than<=: less than or equal to>=: greater than or equal to
While all of these operators are equally important, let's take a closer look at the behavior of the equal (==) and identical (===) operators in the context of objects.
Let's take a look at the following example:
<?php
class User {
public $name = 'N/A';
public $age = 0;
}
$user = new User();
$employee = new User();
var_dump($user == $employee); // true
var_dump($user === $employee); // falseHere, we have a simple User class with two properties set to some default values. We then have two different instances of the same class, $user and $employee. Given that both objects have the same properties, with the same values, the equal (==) operator returns true. The identical...
