how to write an array for keyed list of items in a select list

Hello, I am trying to write a list of allowed items for a form's select list. The CMS system I am on says it wants "a keyed array of items" using the following format:
-----------------------------------------------
The default value PHP code returned an incorrect value.
Expected format:

return array(
  0 => array('value' => value for value),
  // You'll usually want to stop here. Provide more values
  // if you want your 'default value' to be multi-valued:
  1 => array('value' => value for value),
  2 => ...
);

Returned value:

----------------------

Here's what I'm trying to do.

For each item, the key (aka "label") is a name like "kilim" or "gabbeh" and the value is itself a php snippet the looks up data from a database. It is

$term = (array) taxonomy_get_term(64); print "<strong>About" . " ". $term[name] . ":</strong> " . $term[description];

The only thing that changes for each item is the number (64).

Here is the list of keys and corresponding values:

Khorjuns   64
Kilims         4
Kilim pillows 63
Jajims      6
Suzani    99
Sofreh    119
Qashqai     78
Bakhtiari     108
Senneh      102
Shahsavan   80
Afshar       79
Qum      109
Azarbaijan    100
Turkmen     89
Ghoochan    110
Pile       666

I've written the following code and it works when I put it in a text area.

$des [Khorjuns] = $term = (array) taxonomy_get_term(64); print "<strong>About" . " ". $term[name] . ":</strong> " . $term[description];
$des [Kilims] = $term = (array) taxonomy_get_term(4); print "<strong>About" . " ". $term[name] . ":</strong> " . $term[description];
foreach ($des as $value) {

echo $value;

But when I put it in to create a select list, it won't take it, referring me to the aforementioned format it wants. Plus I think my format is needlessly repeating a whole bunch things. The bottom line is I've never really understood array  in php.

Can someone help me how to do this. Please write it out for me or at least write out enough for me to get started. Just saying "you need to use the ... function" will go over my head. Thank you for your patience.

See if this helps understand the use of associative arrays in PHP.  Best regards, ~Ray
<?php // RAY_array_sample_17.php

error_reporting(E_ALL);

echo "<pre>\n";
 

// DEFINE AN EMPTY ARRAY

$arr = array();
 

// ADD SOME KEY => VALUE PAIRS TO THE ARRAY

$arr["Monday"]    = "Lamb Stew";

$arr["Tuesday"]   = "Chicken";

$arr["Wednesday"] = "Soup";

$arr["Thursday"]  = "Roast Beef";

$arr["Friday"]    = "Fresh Fish";
 

// VISUALIZE THE ARRAY

var_dump($arr);
 

// SELECT AN ELEMENT FROM THE ARRAY

echo "\n";

echo "ON THURSDAY WE ARE GOING TO HAVE ";

echo $arr["Thursday"];

echo "\n";
 

// ITERATE OVER THE ARRAY

foreach ($arr as $key => $val)

{

   echo "\n ON $key WE EAT $val";

   if ($key == "Thursday") echo " YUM!";

}

echo "\n\n";
 

// CREATE SELECT-LIST ELEMENTS FROM THE ARRAY

$select_list = "<select>\n";

foreach ($arr as $key => $val)

{

    $select_list .= "<option value=\"$key\">$val</option>\n";

}

$select_list .= "</select>\n";
 

// SHOW THE SELECT LIST

echo htmlentities($select_list);
