Re: [PHP] gettting last assigned key in an array

[Evan Priestley]

function get_last_key( $array ) {
        // end( $array ); return key( $array );
        return array_search(
                 reset( array_reverse( array_values( array_flip( $array ) ) ) )
                ,array_reverse( array_values( array_flip( $array ) ) )
                ,true
                );
        }

i"m mapping some data from a sql select into a custom object that will have a couple associative arrays. I have some code that I think looks a little ugly such as:

        $x=0;
        if($row['slot']>=2)
        {
            $this->menu_item[$x]['item_id']=$row['item_id'];
            $this->menu_item[$x]['name']=$row['name'];
            $this->menu_item[$x]['item_price']=$row['item_price'];
            $x++;
        }

I'd rather do something like this:
        if($row['slot']>=2)
        {
            $this->menu_item[]['item_id']=$row['item_id'];
            $y=get_last_key();
            $this->menu_item[$y]['name']=$row['name'];
            $this->menu_item[$y]['item_price']=$row['item_price'];
        }

but don't know if php has a built in for the "get_last_key()"; any thoughts would be appreciated (including whether you think the original code snippet is fine.
