Dynamically call Class with variable number of parameters in the constructor

Question

I know that it is possible to call a function with a variable number of parameters with call_user_func_array() found here -> http://php.net/manual/en/function.call-user-func

Answer 1

You can do the following using ReflectionClass

$myClass = '\Some\Dynamically\Generated\a';
$myParameters = array ('dynamicparam1', 'dynamicparam2');

$reflection = new \ReflectionClass($myClass); 
$myClassInstance = $reflection->newInstanceArgs($myParameters); 

PHP manual: http://www.php.net/manual/en/reflectionclass.newinstanceargs.php

Edit:

In php 5.6 you can achieve this with Argument unpacking.

$myClass = '\Some\Dynamically\Generated\a';
$myParameters = ['dynamicparam1', 'dynamicparam2'];

$myClassInstance = new $myClass(...$myParameters);
