PHP get_class

PHP original manual for get_class [ show | php.net ]

get_class

(PHP 4, PHP 5, PHP 7)

get_class — Returns the name of the class of an object

Description

string get_class ([ object $object ] )

Gets the name of the class of the given object.

Parameters

object

The tested object. This parameter may be omitted when inside a class.

Note: Explicitly passing NULL as the object is no longer allowed as of PHP 7.2.0. The parameter is still optional and calling get_class() without a parameter from inside a class will work, but passing NULL now emits an E_WARNING notice.

Return Values

Returns the name of the class of which object is an instance. Returns FALSE if object is not an object.

If object is omitted when inside a class, the name of that class is returned.

If the object is an instance of a class which exists in a namespace, the qualified namespaced name of that class is returned.

Errors/Exceptions

If get_class() is called with anything other than an object, an E_WARNING level error is raised.

Changelog

Version Description
7.2.0 NULL was removed as the default value for object, and is no longer a valid input.
5.3.0 NULL became the default value for object, so passing NULL to object now has the same result as not passing any value.

Examples

Example #1 Using get_class()

<?php

class foo {
    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 above example will output:

Its name is foo
My name is foo

Example #2 Using get_class() in superclass

<?php

abstract class bar {
    public function __construct()
    {
        var_dump(get_class($this));
        var_dump(get_class());
    }
}

class foo extends bar {
}

new foo;

?>

The above example will output:

string(3) "foo"
string(3) "bar"

Example #3 Using get_class() with namespaced classes

<?php

namespace Foo\Bar;

class Baz {
    public function __construct()
    {

    }
}

$baz = new \Foo\Bar\Baz;

var_dump(get_class($baz));
?>

The above example will output:

string(11) "Foo\Bar\Baz"
