How about including an example of what comes in $arr when the function is called, what $this->$deptree has to do with anything and what you want the output to look like. I'm not big on OOP, but $this->$deptree does not look right. Also usually when I see a recursive function the values passed to the function when it calls itself are derived from the values passed when it was first called. > function RecPrintDeps($arr, $depth=0){ > //print_r($arr); > $depth++; > printf("<H$depth><a > href=\"%s?dep=%s\">%s</a></H$depth>", $HTTP_SELF, $arr[0], $arr[2]); > while(list($k,$v)=each($this->$deptree)){ > if($v[1]==$arr[0]) > $this->RecPrintDeps($v,$depth); > } > } Rick Widmer Internet Marketing Specialists http://www.developersdesk.com
