[PHP] reference a function in a class from array_walk()

[Thomas Hochstetter]

Hi guys.
I want to call this generic echo function within a class, but have
trouble referencing the output function with $this-> .
Any suggestions? Maybe there is a better solution to this?
 
This is within a class:
 
[snip]
# generic WALK functions
            function walkit($array)
            {
                        array_walk($array,"$this->output"); //not
working
            }
            
            function output($item,$key)
            {
                        echo "$key. $item<br />\n";        
            }
