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";        
           }

"A method of an instantiated object is passed as an array containing an 
object as the element with index 0 and a method name as the element with 
index 1."

function walkit($array){
   array_walk($array,array($this,'output'));
}
function output($item,$key){
   echo "$key. $item<br />\n";
}
