Question

Did my research on this, couldn’t find what I was looking for. Tried ReflectionClass but that didn’t work for me.

I have a class with functions. The number of variables going into the function is dynamic.

Example:

Included class:

class Home {
  function test($var1, $var2, $var3){
    // do stuff here
  }
}

// this class is included based on url params, i.e. example.com/home/test/1/2/3
// where home is class, test is function and 1 2 3 are variables

$variables = array('1','2','3'); // static for this example, but array can have any number of elements to it.

$foo = new Home();
$foo->test($variables);

call_user_func_array('test', $variables);

So what I am trying to achieve, is to take the array of variables and send them to the function test as so in the code example, where I can list each one.

This example below does what I would like to do, but how would I apply it to a class/mvc framework?

$colors = array('test','maroon','blue','green');
call_user_func_array('setLineColor', $colors);

function setLinecolor($var1, $var2, $var3, $var4){
  echo $var1;
  echo $var2;
}

Any thoughts on this?

Use a proper callback for the object:

$foo = new Home();
call_user_func_array( array( $foo, 'test'), $variables);

This will invoke the test() function on the $foo object.
