Question

I am autoloading my classes and want a way to dynamically instantiate the class when used.

Instead of having 20 class instantiations in my parent class, I want a way to instantiate a class when its being called.

for example:

$this->template->render();

will instantiate

$this->template = new Template();

I attempted this

public function __set($name, $value)
{
    return $this->$name;
}

public function __get($name)
{
    $this->$name = new $name();
}

This doesn’t seem to work, but I also think I’m doing it wrong.

One issue that I can’t figure out also is that my classes reside in the \System namespace. I can’t seem to tack on new "\System".$name() or new \System.$name() without getting an error;

private $_template;
public function __set($name, $value)
{
  $this->{'_' . $name} = $value;
}

public function __get($name)
{
  if (!$this->{'_' . $name}) {
    $classname = '\\System\\' . ucfirst($name);
    $this->{'_' . $name} = new $classname();
  }
  return $this->{'_' . $name};
}
