Passing array of parameters to object constructor

Question

How can I call a object constructor passing an array of parameters so that having:

$array = array($param1, $param2);

I'll be able to call

$abc = new Abc($param1, $param2);

considering that I don't know how many parameters could be set in the array. Is there something like call_object('Abc', array($param1, $param2))?

Answer 1

How about using ... (splat operator)?

$array = array($param1, $param2);
$abc = new Abc(...$array); // equal to: new Abc($param1, $param2)

PHP 5.6 is required.

Answer 2

The best way is to use an array or object that stores the arguments and you just pass that array/object

Another way would be using Reflection ( http://de2.php.net/Reflection ) using newInstanceArgs ( http://de2.php.net/manual/de/reflectionclass.newinstanceargs.php )
