Note Submitter: brettz9 ---- If you have a multi-dimensional array and wish to remove duplicates from a particular "column" as well as the corresponding values in the other "columns", you might find the following helpful. <?php function remove_dups($array, $index) { $array_count = count($array); $array_count_inner = count($array[$index]); for ($i=0; $i<$array_count_inner; $i++) { for ($j=$i+1; $j<$array_count_inner; $j++) { if ($array[$index][$i]==$array[$index][$j]) { for ($k=0; $k<$array_count; $k++) { unset($array[$k][$i]); } // end for } // end if } // end for } // end for return $array; } // end function remove_dups ?>
