Question

I’m currently doing this but it doesn’t look right to me:

spl_autoload_register(function ($class_name){
    $class_name = str_replace('MyNameSpace\\', '', $class_name . '.php');

    require $class_name;
});

Please advise.

Answer 1

The namespace is passed because it has to be. How else would the autoloader function know the difference between Foo\Bar and Baz\Bar? 🙂

Your method looks okay if you’re absolutely sure that you won’t ever need to load classes with the same names as those found in MyNameSpace. The canonical method to autoloading classes involves using the parts of the namespace as file system structure, so that, for example, foo\bar\Baz can be found at path foo/bar/Baz.php.
