Question

ok so i am creating a multidementional array and this line only allows one element into it. How do i check to see if

$related[$row_r['Category_name']][$row_r['name']]

is greater then 0 and if so dont overwrite the value and just append onto it

while($row_r = mysql_fetch_assoc($result)){
  $related[$row_r['Category_name']][$row_r['name']] = $row_r; //this line

Perhaps you’re looking for this?

while($row_r = mysql_fetch_assoc($result)){
    $related[$row_r['Category_name']][$row_r['name']][] = $row_r;
}
