<?php

function test(string $param1, string $param2): void
{
    echo $param1.' '.$param2;
}

$args = ['hello', 'world'];
//hello world
call_user_func_array('test', $args);

$args = ['param2' => 'world', 'param1' => 'hello'];
//hello world
call_user_func_array('test', $args);

$args = ['unknown_param' => 'hello', 'param2' => 'world'];
//Fatal error: Uncaught Error: Unknown named parameter $unknown_param
call_user_func_array('test', $args);
