Need function similar to implode()

[mattfletcher]

Hi, I need a function that is similar to implode(), but joins the penultimate and last elements differently.

Four examples:

Joe, John, Jim and Jane
Fred, Frank and Flo
Sally and Sarah
Daniel

Maybe I could use some sort of regex on an imploded string?

A working example would be greatly appreciated.

Something like this should suit:

function fancy_join($list, $glue=', ', $final_glue=' and ') { 
 if (count($list)) == 0) return null; 
 if (count($list)) == 1) return $list[0]; 
 $last = array_pop($list); 
 return implode($glue, $list) . $final_glue . $last; 
}
