How can I call a static method from a class if all I have is a string of the class name?

Question

How would I get something like this to work?

$class_name = \'ClassPeer\';
$class_name::doSomething();

Answer 1

if you need to adjust the namespace

$call = call_user_func(array('\\App\\Models\\'.$class_name, "doSomething"));
