note 92514 added to function.spl-autoload-register

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.
