Question

Let’s pretend this is happening inside of a class method (pure example):

public function runEvent($funcName, $params)
{
 $funcName($this, $params);
}

//somewhere else
function myFunc($anBOject, $paramsHere, $somethingElse = NULL)
{
 //do stuff
}

$SomeClassObj->runEvent('myFunc', array('dog', 'cat'));

Can I assume PHP will execute myFunc with the first parameter being $this, second being $params, and then NULL as the 3rd param (by default)?

This question is more just for understanding how PHP deals with variable functions. Im not actually having any issues in a certain project.

Thanks!

Answer 1

Yes.

$funcName($this, $params);

is called exactly the same way as

myFunc($this, $params);

The first parameter is $this, the second $params, there’s no third.

To call functions with a variable number of arguments, use call_user_func_array.
