How can I call a static method from a class if all I have is a string of the class name?
Depending on version of PHP:
call_user_func(array($class_name, 'doSomething'));
call_user_func($class_name .'::doSomething'); // >5.2.3
To unleash the power of IDE autocomplete and error detection, use this:
$class_name = 'ClassPeer';
$r = new \ReflectionClass($class_name );
// @param ClassPeer $instance
$instance = $r->newInstanceWithoutConstructor();
//$class_name->doSomething();
$instance->doSomething();
Basically here we are calling the static method on an instance of the class.
