PHP: How to use dynamic variable name with a class' setter

dynamic-variables, php

Solution

<?php
$bar = "description";
$f = new Foo();
$func="set"+ucwords($bar);
$f->$func("asdf");
?>

Problem

I have a class with a private member "description" but that proposes a setter : ``` class Foo { private $description; public function setDescription($description) { $this->description = $description; } } ``` I have the name of the member in a variable. I would like to access the field dynamically. If the field was simply public I could do : ``` $bar = "description"; $f = new Foo(); $f->$bar = "asdf"; ``` but I don't know how to do in the case I have only a setter.
