PHP Array Help $key=>$value

[boxfan]

I am trying to do the following:

while ($row = $conn->fetch_object ()) {
  foreach($row as $key=>$value) { $$key[] = $value; } 
}

Obviously the $$key[] = $value is incorrect but you can see what I'm trying to accomplish. I want the DB field names to become arrays holding the multiple rows of data without having to specifically assign like this

$orderDate[] = $row->orderDate;
$orderAmount[] = $row->orderAmount; 

Any ideas?

Thanks.

Nevermind. I figured it out.

while($row = $conn->fetch_array()){
foreach($row as $key => $value){
if(!is_numeric($key)){
$array[$key][] = $value;
$$key = $array[$key];
}
}
}

Thanks
