php building / populating an Array of Arrays - php

Question

I have seen alot of tutorial on how to get the data out of a 2D array but I need to build one similar to this and I have not found any logic I can follow:
$array = array("socks" => array("blue", "red", "green"),
"shirts" => array("small", "medium", "large"));
I cant seem to figure out the logic to even start the code....
for each clothingType // I did this
get options // I did this
for each option //I did this
add to the clothingOption Array //... help!
Im only stuck on the building of the clothingOption 2D Array
could it be someting like
foreach clothingType as $kClothes =>VClothes
get Options
for each Options as $kOptions =>$VOption
$array[$VClothes][]= $VOption
Thanks and I hope this is not too vague....

Answer 1

How about the following?
<?php
function getMe($type) {
//do some processing and construct array
return array('a','b','c');
}
$myTypes = array('type1','type2','type3');
$answer = array();
foreach($myTypes as $val) {
$answer[$val] = getMe($val);
}
print_r($answer);
?>
Output:
Array ( [type1] => Array ( [0] => a [1] => b [2] => c ) [type2] => Array ( [0] => a [1] => b [2] => c ) [type3] => Array ( [0] => a [1] => b [2] => c ) )

Answer 2

maybe (sorry for errors - by hand):
//$array = array("socks" => array("blue", "red", "green"),
// "shirts" => array("small", "medium", "large"));
$types = array('socks', 'shirts');
$socks = array("blue", "red", "green");
$shirts = array("small", "medium", "large");
$array = array();
foreach ($types as $type) {
foreach($$type as $cloth) {
$array[$type][] = $cloth;
}
}
print_r($array);
