PHP - 使用可变数量的参数调用__invoke

Question

Is it possible, with some kind of dirty trick possibly, to invoke a class via the __invoke magic method using a variable number of arguments?

I know that in php 5.6 there are variadics, but my version is not there yet...

For a normal class method I could try to do something using the magic method __call and the call_user_func_array function. What about the __invoke magic method?

Answer 1

Seems to be possible with func_get_args():

Adjusting the example from the docs:

<?php
class CallableClass
{
    public function __invoke()
    {
        var_dump(func_get_args());
    }
}
$obj = new CallableClass;
$obj(5, 6, 7, 8); // vary arguments to meet your needs
