PHP: Array to variable function parameter values

Question

I have a variable length array that I need to transpose into a list of parameters for a function.

I hope there is a neat way of doing this - but I cannot see how.

Yes, use call_user_func_array():

call_user_func_array('function_name', $parameters_array);

You can use this to call methods in a class too:

class A {
  public function doStuff($a, $b) {
    echo "[$a,$b]\n";
  }
}

$a = new A;
call_user_func_array(array($a, 'doStuff'), array(23, 34));
