get_class
Returns the name of the class of an object
Description
string get_class(object $object = ?)
Parameters
-
object
-
The tested object.
Note:
Explicitly passing null as the object is no
longer allowed as of PHP 7.2.0 and emits an E_WARNING.
As of PHP 8.0.0, a TypeError is emitted when
null is used.
Return Values
Returns the name of the class of which object is an
instance.
If the object is an instance of a class which exists
in a namespace, the qualified namespaced name of that class is returned.
Errors/Exceptions
If get_class is called with anything other than an
object, TypeError is raised. Prior to PHP 8.0.0,
an E_WARNING level error was raised.
If get_class is called with no arguments from outside a class,
an Error is thrown. Prior to PHP 8.0.0,
an E_WARNING level error was raised.
Examples
Example #1 Using get_class
<?php
class foo {
function name()
{
echo "My name is " , get_class($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:
