Good news for PHP 5.3 users with namespaced classes:
When you create a subfolder structure matching the namespaces of the containing classes, you will never even have to define an autoloader.
<?php
spl_autoload_extensions(".php"); // comma-separated list
spl_autoload_register();
?>
It is recommended to use only one extension for all classes. PHP (more exactly spl_autoload) does the rest for you and is even quicker than a semantically equal self-defined autoload function like this one:
<?php
function my_autoload ($pClassName) {
include(__DIR__ . "/" . $pClassName . ".php");
}
spl_autoload_register("my_autoload");
?>
I compared them with the following setting: There are 10 folders, each having 10 subfolders, each having 10 subfolders, each containing 10 classes.
To load and instantiate these 1000 classes (parameterless no-action constructor), the user-definded autoload function approach took 50ms longer in average than the spl_autoload function in a series of 10 command-line calls for each approach.
I made this benchmark to ensure that I don't recommend something that could be called "nice, but slow" later.
Best regards,
spl_autoload_register

spl_autoload_register — Register given function as __autoload() implementation
Beschreibung
Register a function with the spl provided __autoload queue. If the queue is not yet activated it will be activated.
If your code has an existing __autoload() function then this function must be explicitly registered on the __autoload queue. This is because spl_autoload_register() will effectively replace the engine cache for the __autoload() function by either spl_autoload() or spl_autoload_call().
If there must be multiple autoload functions, spl_autoload_register() allows for this. It effectively creates a queue of autoload functions, and runs through each of them in the order they are defined. By contrast, __autoload() may only be defined once.
Parameter-Liste
-
callback -
The autoload function being registered. If
null, then the default implementation of spl_autoload() will be registered.The
classwill not contain the leading backslash of a fully-qualified identifier. -
throw -
This parameter specifies whether spl_autoload_register() should throw exceptions when the
callbackcannot be registered.WarnungThis parameter is ignored as of PHP 8.0.0, and a notice will be emitted if set to
false. spl_autoload_register() will now always throw a TypeError on invalid arguments. -
prepend -
If true, spl_autoload_register() will prepend the autoloader on the autoload queue instead of appending it.
Rückgabewerte
Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.
Changelog
| Version | Beschreibung |
|---|---|
| 8.0.0 |
callback is now nullable.

Beispiele
Beispiel #1 spl_autoload_register() as a replacement for an __autoload() function
<?php
// function __autoload($class) {
// include 'classes/' . $class . '.class.php';
// }
function my_autoloader($class) {
include 'classes/' . $class . '.class.php';
}
spl_autoload_register('my_autoloader');
// Or, using an anonymous function
spl_autoload_register(function ($class) {
include 'classes/' . $class . '.class.php';
});
?>Beispiel #2 spl_autoload_register() example where the class is not loaded
<?php
namespace Foobar;
class Foo {
static public function test($class) {
print '[['. $class .']]';
}
}
spl_autoload_register(__NAMESPACE__ .'\Foo::test');
new InexistentClass;
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
[[Foobar\InexistentClass]] Fatal error: Class 'Foobar\InexistentClass' not found in ...
Beispiel #3 The identifier will be provided without the leading backslash
<?php
spl_autoload_register(static function ($class) {
var_dump($class);
});
class_exists('RelativeName');
class_exists('RelativeName\\WithNamespace');
class_exists('\\AbsoluteName');
class_exists('\\AbsoluteName\\WithNamespace');
?>Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
string(12) "RelativeName" string(26) "RelativeName\WithNamespace" string(12) "AbsoluteName" string(26) "AbsoluteName\WithNamespace"

Even when autoloading (SPL) is used, class inheritance does not seem to work. Simply the PHP engine is unable to find parent (inherited) class. PHP 5.6 and 7.0 behave exactly same on this, which beats the purpose of autoloading.
And IMHO it's easy to fix as the autoloader is able to find all first level classes w/o problems, it just needs to follow same path recursively on parents too.
<?php
//Using default SPL autoloader, with namespaces mapping 1:1 to directory structure, with file names being all lowercase.
//This works with first level classes only, for inheritance it does NOT work, it cannot find parent classes.
spl_autoload_register();
//This is ugly but working code if you want to be able to autoload parent classes too.
spl_autoload_register(function ($class){
require_once __DIR__ . '/' . strtolower(str_replace('\\', '/', $class) . '.php');
});

Since PHP 8.0 spl_autoload_register() will always throw a TypeError on invalid arguments, therefore the second argument `throw` is ignored and a notice will be emitted if it is set to False.

When switching from using __autoload() to using spl_autoload_register keep in mind that deserialization of the session can trigger class lookups.
This works as expected:
<?php
session_start();
function __autoload($class) {
...
}
?>
This will result in "__PHP_Incomplete_Class_Name" errors when using classes deserialized from the session.
<?php
session_start();
function customAutoloader($class) {
...
}
spl_autoload_register("customAutoloader");
?>
So you need to make sure the spl_autoload_register is done BEFORE session_start() is called.
CORRECT:
<?php
function customAutoloader($class) {
...
}
spl_autoload_register("customAutoloader");
session_start();
?>

When using spl_autoload_register() with class methods, it might seem that it can use only public methods, though it can use private/protected methods as well, if registered from inside the class:
<?php
class ClassAutoloader {
public function __construct() {
spl_autoload_register(array($this, 'loader'));
}
private function loader($className) {
echo 'Trying to load ', $className, ' via ', __METHOD__, "()\n";
include $className . '.php';
}
}
$autoloader = new ClassAutoloader();
$obj = new Class1();
$obj = new Class2();
?>
Output:
--------
Trying to load Class1 via ClassAutoloader::loader()
Class1::__construct()
Trying to load Class2 via ClassAutoloader::loader()
Class2::__construct()

Think twice about throwing an exception from a registered autoloader.
If you have multiple autoloaders registered, and one (or more) throws an exception before a later autoloader loads the class, stacked exceptions are thrown (and must be caught) even though the class was loaded successfully.

If your autoload function is a class method, you can call spl_autoload_register with an array specifying the class and the method to run.
* You can use a static method :
<?php
class MyClass {
public static function autoload($className) {
// ...
}
}
spl_autoload_register(array('MyClass', 'autoload'));
?>
* Or you can use an instance :
<?php
class MyClass {
public function autoload($className) {
// ...
}
}
$instance = new MyClass();
spl_autoload_register(array($instance, 'autoload'));

Be careful using this function on case sensitive file systems.
<?php
spl_autoload_extensions('.php');
spl_autoload_register();
?>
I develop on OS X and everything was working fine. But when releasing to my linux server, none of my class files were loading. I had to lowercase all my filenames, because calling a class "DatabaseObject" would try including "databaseobject.php", instead of "DatabaseObject.php"
I think i'll go back to using the slower __autoload() function, just so i can keep my class files readable

What I said here previously is only true on Windows. The built-in default autoloader that is registered when you call spl_autoload_register() without any arguments simply adds the qualified class name plus the registered file extension (.php) to each of the include paths and tries to include that file.
Example (on Windows):
include paths:
- "."
- "d:/projects/phplib"
qualified class name to load:
network\http\rest\Resource
Here's what happens:
PHP tries to load
'.\\network\\http\\rest\\Resource.php'
-> file not found
PHP tries to load
'd:/projects/phplib\\network\\http\\rest\\Resource.php'
-> file found and included
Note the slashes and backslashes in the file path. On Windows this works perfectly, but on a Linux machine, the backslashes won't work and additionally the file names are case-sensitive.
That's why on Linux the quick-and-easy way would be to convert these qualified class names to slashes and to lowercase and pass them to the built-in autoloader like so:
<?php
spl_autoload_register(
function ($pClassName) {
spl_autoload(strtolower(str_replace("\\", "/", $pClassName)));
}
);
?>
But this means, you have to save all your classes with lowercase file names. Otherwise, if you omit the strtolower call, you have to use the class names exactly as specified by the file name, which can be annoying for class names that are defined with non-straightforward case like e. g. XMLHttpRequest.
I prefer the lowercase approach, because it is easier to use and the file name conversion can be done automatically on deploying.

It is never a good idea and a unconscienable concept to create the classes in the autoload function via eval.
It should be a nice feature with these Exception, but i think anyone is able to handle it without this method although. Atm i dont realize for what this is good for...
As i might note, class_exists() will ever define the classes u only want to check for existance, and will therefor ever return true:
<?php
function EvalIsEvil($class) {
eval('class '.$className.'{}');
}
spl_autoload_register('EvalIsEvil');
if (class_exists($s="IsMyModuleHere")) {
// this is no module, but get there with eval()...
return new $s();
}
?>

It is important to note that the autoloader will NOT be called if an E_STRICT error triggers the error handler which, in turn, tries to use classes which are not yet loaded.
In this instance, you should manually load classes required by the error handler.

I now utilize spl_autoload_register and there's no turning back. So let me gather here for you what I've learned...
1.) the issue mentioned in these docs about case-sensitivity of filenames (Windows vs Linux/Mac): it only comes into play if you don't provide your own custom function as an argument when calling spl_autoload_register. Your function is to accept a single argument which will be the class name that your code is currently trying to access. I observe that the class name comes in with the same letter-casing as that you are actually using in your code base (mixed-case or not). I am not doing/using namespaces, but as a best practice, and to make your implementation straight-forward and predictable, go with fileName===className (1:1).
2.) I often refactor my code-base's directory structure as my code base morphs. I'm not using namespaces, but even if I were, I would want a decoupling between my namespace hierarchy and my directory structure hierarchy. I like my directory hierarchies to be intuitive for getting to code I want to work with. To save myself from having to manually tell my autoloader the path to each file/class, I cache a couple of arrays in static variables that store just the file/class name in the one array and the folder path to the file in the other. After the cache (static vars) have been set on the first call to my function, it's just a matter of looking up in the filename array. For safety, and to be problem-free, no two php filenames should be identical across all of your directory hierarchy (your namespace)--I favor this practice anyways, and accordingly, I favor unique class names across my single namespace (despite it not yet explicitly defined). I did build in a check in my function to ensure all php file names/classes are unique.
3.) I converted many, many files that once had sets of functions in the global space to *abstract classes* that have private static variables and methods and of course also public static methods. So those sets of functions are now encapsulated in objects, and those objects are now auto-loaded. Simply for this benefit I will never again have a function in the global space other than my auto-loader function and other exceptions such as that.
4.) My auto-loader function uses only built-in php language constructs and operations and has no outside dependencies.
5.) If you utilize the function class_exists() in your codebase somewhere, realize that unless you are passing the second arg as false, you will trigger the autoloader to load that class. I stumbled on this of course. My use-case is that I don't want the class loaded: I only wanted to take some action if the class was being used (in an error-handler method).
6.) If you use the function method_exists(), you will definitely trigger the class to be loaded (which makes sense since you have already decided to drill down to looking for a specific method).
7.) I credit someone else's idea here: I also elected to call an init() method for the class being loaded should it exist. This saves me from having to manually call from the outside, let alone managing how and from where the call should be made. It is so useful to get your object set up and ready to do work in an automated fashion such as this.
8.) as another said, I also use require() and not require_once() as the first is enough to generate an error and if already loaded the function will not have been called.
9.) If for some reason I fail to find a class name in my cached arrays, I knowingly still call require(), passing the class name I had not accounted for in order to generate and reveal the problem (which of course is not anticipated!).
10.) Again, I ensure uniqueness across all class names. If I observe non-uniqueness, I again do a faulty call to require() like this: require('FoundMultiplesOfClassFile.php'); to reveal the problem. (I don't yet, and you likely should not, have any sophisticated error-handler registered so this is as good as anything else to me).

Cleverly - and usefully - I have noticed that (on PHP 5.3 at least) these autoloaders "kick in" even when you call a public static method of an as-yet-unloaded all static class.

It seems, that spl_autoload tests, if the class exists, after calling every registered loader. So it breaks the chain, if the class exists and will not call the other loaders
<?php
function a ($c) {
echo "a\n";
class Bla {} // Usually "include 'path/to/file.php';"
}
function b ($c) {
echo "b\n";
}
spl_autoload_register('a');
spl_autoload_register('b');
$c = new Bla();

Editorial note: The appropriate PHP bug that requests behavior this function emulates is http://bugs.php.net/bug.php?id=42823 . This function does NOT work if there has been an array($obj, 'nonStaticMethod') registered in the autoload stack--while the autoload will be removed, it will be re-registered incorrectly.
The spl_autoload_register() method registers functions in its stack in the order that spl_autoload_register() was called, and subsequently if you want an autoload function to override previous autoload functions you will either need to unregister the previous ones or change the order of the autoload stack.
For example, say in your default implementation of an autoload function you throw an exception if the class cannot be found, or perhaps a fatal error. Later on in your code you add a second implementation of an autoload function which will load a library that the previous method would fail on. This will not call the second autoloader method first, but rather will continue to error out on the first method.
As previously mentioned, you can unregister the existing autoloader that errors out, or you can create a mechanism for unregistering and re-registering the autoloaders in the order you want.
Here is a sample/example of how you might consider re-registering autoloaders so that the newest autoloader is called first, and the oldest last:
<?php
// Editorial notes: Small bug and compatibility fixes
// added to the function
function spl_autoload_preregister( $autoload ) {
// No functions currently in the stack.
if ( ($funcs = spl_autoload_functions()) === false ) {
spl_autoload_register($autoload);
} else {
// Unregister existing autoloaders...
$compat =
version_compare(PHP_VERSION, '5.1.2', '<=') &&
version_compare(PHP_VERSION, '5.1.0', '>=');
foreach ($funcs as $func) {
if (is_array($func)) {
// :TRICKY: There are some compatibility issues and some
// places where we need to error out
$reflector = new ReflectionMethod($func[0], $func[1]);
if (!$reflector->isStatic()) {
throw new Exception('
This function is not compatible
with non-static object methods due to PHP Bug #44144.
');
}
// Suprisingly, spl_autoload_register supports the
// Class::staticMethod callback format, although call_user_func doesn't
if ($compat) $func = implode('::', $func);
}
spl_autoload_unregister($func);
}
// Register the new one, thus putting it at the front of the stack...
spl_autoload_register($autoload);
// Now, go back and re-register all of our old ones.
foreach ($funcs as $func) {
spl_autoload_register($func);
}
}
}
?>
Note: I have not tested this for overhead, so I am not 100% sure what the performance implication of the above example are.

If you want to be able to run your PHP script from anywhere without changing to the directory first, use chdir(__DIR__) in the first file you run (not any includes):
<?php
spl_autoload_register();
chdir(__DIR__);
For some reason, trying to use namespaced classes from within other namespaced classes fails otherwise.
e.g. Running "php src/main.php" will fail, but "cd src && php main.php" will work.
src/main.php
<?php
spl_autoload_register();
//chdir(__DIR__); // Uncomment this to make it work from any directory
MyNamespace\MyClass::foo();
src/MyNamespace/MyClass.php
<?php
namespace MyNamespace;
class MyClass {
public static function foo(): void {
echo MyOtherClass::BAR; // This will fail even if MyOtherClass.php is in the right place
}
}
src/MyNamespace/MyOtherClass.php
<?php
namespace MyNamespace;
class MyOtherClass {
public const BAR = 'baz';
}

If you need to register the function when using namespaces, use the __NAMESPACE__ constant to define the name.
<?php
namespace Foobar;
spl_autoload_register('MyFunction'); // incorrect
spl_autoload_register('\MyFunction');// incorrect
spl_autoload_register(__NAMESPACE__ . '\MyFunction'); // correct

This function is smart enough not to add the same loader twice. This seems to work for all of the different loader formats. Example:
<?php

static function load($class) { return true; }
}
function anotherLoader($class) {
return true;
}
$F = new ALoader;
spl_autoload_register(array('ALoader', 'load'));
spl_autoload_register(array('ALoader', 'load'));
spl_autoload_register(array($F, 'load'));
spl_autoload_register('anotherLoader');
spl_autoload_register('anotherLoader');
var_dump(spl_autoload_functions());
/*
* Results on PHP5.2 CLI, linux.
* array(2) {
* [0]=>
* array(2) {
* [0]=>
* string(7) "ALoader"

if you have a dir-structure like "/abc/def/ghi", your index.php lies in the top directory, but you want to use namespaces starting with "def" or "ghi":
you can switch the namespace root directory of php with e.g. set_include_path(__DIR__ . '/abc') and afterwards define + use your namespaces with the simple spl_autoload_register() function without any arguments supplied.
remember that php handlers "cli" and "cli-server" are special cases.

This autoload will find every class you call if you put each one in a different file.
It walks into every directory recursivly from the root you specify in the $root var.
You can specify the folders ou don't want to walk in (e.g you won't find any class in a 'view' folder on an MVC project) in the $dir_to_not_look_in array;
spl_autoload_register(function($class) {
$root = 'my/root/path';
$file = $class . '.php';
$dir_to_not_look_in = array($directories, $to, $not, $look, $in);
if(!function_exists('load')) {
function load($dir, $file) {

} else {

spl_autoload_register() can be used with include_path.
suppose in current directory we have directory "a", and inside there is directory "test" and inside is test.php :
<?
namespace test;
class test{
function __construct(){
echo "Test created\n";
}
}
?>
then we can use following code to load the class:
<?
ini_set("include_path", "./a/");
spl_autoload_register();
$t = new \test\test();

You can also use it like this:
> spl_autoload_register ( array( new AutoloaderClass, 'method') );
or in PHP > 5.3:
> spl_autoload_register ( [ new My\Namespace\Autoloader, 'method'] );
On this way you dont have to create a variable, which is used once.

I've made a little function that makes and registers a loader that seems to be safe and reliable although I'm not sure but it feels like a good idea to share, it took me some time to come up with it I hope it saves someone some time,
<?php
function Loader($root = "") {
$loaderFunction = create_function('$class', 'include "' . $root . '$class.php";');
spl_autoload_register($loaderFunction);
}
?>
if you have a file system exactly like your directory tree this function works perfectly, I haven't tested it on unix, but on windows, the default loader fails when your webpage isn't in the root directory, this makes sure that it won't cause a problem if your webpage is on a subdir too just pass ../ or more drived ../../ as root and it will work like a charm, note that i couldn't use anonymous functions because then the $root variable wouldn't have the same scope as the Loader function, so the function must be created on the fly. this is a good example of this functions usage
your class:
root/classes/support/classic.php
<?php
namespace classes/support;
class classic {
// class def
}
?>
root/support/index.php
<?php
Loader('../');
use classes/support/classic;
$cls = new classic();
//use $cls
?>
the loader will make a function like this:
<?php
function($class) {
include "../$class.php";
}
//when and when the class is needed this will run the script which is indeed what we need:
include '../classes/support/classic.php';
?>
hope this helps folks;
