Adjusting an array...

Below is an array.  I'm trying to build a select a menu based on it.  

I want the select menu to look like this:

<select name = "size">
  <option value="X879">small / medium </option>
  <option value="7ABC">small / large </option>
</select>

I can't figure out how to "group" them that way... :(
Array
(
    [0] => Array
        (
            [item_id] => 32
            [oid] => X879
            [name] => size
 	    [value] => small
            [id] => 2
            [aid] => 10
        )
 
    [1] => Array
        (
            [item_id] => 32
            [oid] => X879
            [name] => size
	    [value] => medium
            [id] => 2
            [aid] => 14
        )
 
    [2] => Array
        (
            [item_id] => 32
            [oid] => 7ABC
            [name] => size
	    [value] => small
            [id] => 2
            [aid] => 10
        )
 
    [3] => Array
        (
            [item_id] => 32
            [oid] => 7ABC
            [name] => size
	    [value] => large
            [id] => 2
            [aid] => 130
        )
 
)

Try a for loop on it, and use the key of the array. Example:

$count_of_array = count($array);
echo '<select name="size">';
for($i=0; $i<$count_of_array; $i++){
  echo '<option value="'.$array[1]."'>'.$array[3].'</option>';
}
echo '</select>';

Actually, the item_id and name will change, depending on what's retrieved from the database.  I tried:



$array = array();
foreach($options as $key => $value) {
  $name = $value['name'];
  unset($value['name']);
  if(isset($array[$name])) $array[$name][] = $value;
  else $array[$name] = array($value);
}


Which kinda redoes the array so that it's "grouped" by size, but I don't know how to then group it by oid.  I thought if I could get that far, that I could build the select accordingly.

$array = array();
foreach($options as $key => $value) {
  $name = $value['name'];
  $optname = $value['oid'];
  unset($value['name']);
  unset($value['oid']);
 
   
    if(isset($array[$name][$optname])) {
        $array[$name][$optname] = $value;
    } else {
        $array[$name][$optname] = array($value);
    }
}

Oops... The code in my last post almost gets me the array I need, except that it only prints out one group per oid, when it should be printing out two.

Ok, so I have the array grouped the way I want, but can't figure out how to build the select menu based on it:

foreach($options as $key => $value) {
	$name = $value['name'];
	$optname = $value['oid'];
	unset($value['name']);
	unset($value['oid']);
	 
		if(isset($array[$name][$optname])) {
			$array[$name][$optname][] = $value;
		} else {
			$array[$name][$optname] = array($value);
		}
}

Thanks for this.  I've made progress towards what I wanted, and now have a related, but different question to ask.  So, I'm going to open up another thread. :)
