How to pass array of arguments to an method

Question

I am trying to pass array to a method and I want the method use array's values as arguments.

I posted a similar question on How to assign arrays to functions arguments? thread but I am actually working on the class method here.

if (method_exists($testInstance, $method)){
  $a=array {'1'=>'aru1', '2'=>'arg2'}   //could have more than 2. it's dynamic
  call_user_func_array($testInstance->$method(), $a);  //this won't work.
}

Any thoughts? Thank a lot!

Mmmh... have you considered reading the documentation (second example)? php.net/manual/en/function.call-user-func-array.php ... also it is helpful to follow further links, read about callbable: php.net/manual/en/language.types.callable.php — Felix Kling

@FelixKling It seems only work in Static method. Am I wrong? — FlyingCat

Works perfectly fine with normal methods. The example shows: /* Call the $foo->bar() method with 2 arguments*/ $foo = new foo; call_user_func_array(array($foo, "bar"), array("three", "four"));. Also this has been asked before and this is the answer: stackoverflow.com/a/745112/218196. Why do you think the method must be static? — Felix Kling

As Felix suggested you need to pass a callable. For a class method that is an array with the object inatance (or class name if it is a static method) and the method name:

call_user_func_array(array($obj,'myMethod'), $args)
