如何在PHP中自动加载函数

Question

I use this code to load classes

 function __autoload($className)
 {
      $files = dirname(__FILE__).'/public/class/'.$className.'.php';

      if(file_exists($files))
      {
           include_once($files);
      }
 }

does anyone know how to retrieve the function automatically, too? Thank you.

Answer 1

Autoloader function registered spl_autoload_register() can be used to load classes, but not functions. Wrap your functions in class or classes to utilize autoloading, i.e.

class Utils {
  static function foo() {
    ..
  }
}

then call it static way:

Utils::foo();

and you can have it autoloaded when needed. See more infromation on autoloading in PHP manual.
