PHP Question

dynamic class property $$value in php

How can i reference a class property knowing only a string?

class Foo
public $bar;

public function TestFoobar()

public function foobar($string)
echo $this->$$string; //doesn't work

what is the correct way to eval the string?


You only need to use one $ when referencing an object's member variable using a string variable.

echo $this->$string;
