spl_autoload在命名空间目录结构之后找不到类

Question

I'm trying to use class autoloading in my project. This is what I wrote:

on main.php:

namespace myproject;

spl_autoload_extensions(".php");
spl_autoload_register();

subspace\myclass::mystaticmethod();

on subspace/myclass.php:

namespace myproject\subspace;

class myclass {

    static function mystaticmethod() {

        ....

    }

}

I get this error:

 PHP Fatal error:  Class 'myproject\\subspace\\myclass' not found

So far I've only found a problem with case sensitive names in the documentation, so I switched to lowercase only but I get the same error. Why?

[EDIT] Using PHP 5.3.3

Answer 1

I've found the problem: The default include directory would be the full namespace/subspace path.

I've also found a good solution. From http://www.php.net/manual/en/function.spl-autoload.php#92767:

<?php
    // Add your class dir to include path
    set_include_path(get_include_path().PATH_SEPARATOR.'..');

    // Make autoloader look for commonly used "myclass.php" type filenames
    spl_autoload_extensions('.php');

    // Use default autoload implementation
    spl_autoload_register();
?>

The default autoload implementation is written in C and is always slightly faster than a PHP one.
