<?php
define(&#39;CLI_SCRIPT&#39;, true);
$user = new stdClass();
$user->id = 1;
$user->name = &#39;tony&#39;;
$user->age = 23;
var_dump($user);
unset($user->name);
var_dump($user);

unset() destroys the specified variable.

The behavior of unset() in a function will vary depending on the type of variable you want to destroy.

If you unset() a global variable in a function, only the local variable will be destroyed, and the variables in the calling environment will maintain the same value before calling unset().
