The spl_autoload_functions Function

The spl_autoload_functions function returns an array of all autoload functions registered with spl_autoload_register. If no autoloaders are registered, the function will return an empty array.

Syntax

spl_autoload_functions();

Example

Let's check the list of registered autoloaders without registration:

<?php
	$res = spl_autoload_functions();
	print_r($res);
?>

Code execution result:

[]

Example

Let's register an autoloader and check the result:

<?php
	function my_autoload($class) {
		include $class . '.php';
	}
	
	spl_autoload_register('my_autoload');
	$res = spl_autoload_functions();
	print_r($res);
?>

Code execution result:

['my_autoload']

Example

Let's check several registered autoloaders:

<?php
	function autoload1($class) {
		// implementation 1
	}
	
	function autoload2($class) {
		// implementation 2
	}
	
	spl_autoload_register('autoload1');
	spl_autoload_register('autoload2');
	$res = spl_autoload_functions();
	print_r($res);
?>

Code execution result:

['autoload1', 'autoload2']
