# get_class

(PHP 4 , PHP 5)

get_class -- Returns the name of the class of an object

## Description

string get_class ( object obj)

This function returns the name of the class of which the object obj is an instance. Returns `FALSE` if obj is not an object.

> 備注: A class defined in a PHP extension is returned in its original notation. In PHP 4 get_class() returns a user defined class name in lowercase, but in PHP 5 it will return the class name in it's original notation too, just like class names from PHP extensions.

示範 1.Using get_class()
`<?php class foo { function foo() { // implements some logic } function name() { echo "My name is " , get_class($this) , "\n"; } } // create an object $bar = new foo(); // external call echo "Its name is " , get_class($bar) , "\n"; // internal call $bar->name(); ?>`
The output is:
    Its name is foo
    My name is foo
