PHP Question
dynamic class property $$value in php
How can i reference a class property knowing only a string?
class Foo
{
public $bar;
public function TestFoobar()
{
$this->foobar('bar');
}
public function foobar($string)
{
echo $this->$$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;
