foreach inside foreach only returns last result?

I'm relatively new to PHP and arrays are giving me fits! I'm attempting to learn how to modify arrays and create new arrays from the modifications, but my attempts are only returning the last array key in the foreach loop.

function stuff() {
  $items = array('shirt', 'shoes', 'pants');
  $colors = array('red', 'blue', 'green');
  $list = array();
  foreach($items as $item) {
    foreach($colors as $color) {
      $list[$item] = array($color => 'available');
    }
  }
  return $list;
}

What I want this to return is:

Array
(
  [shirt] => Array
  (
    [red] => available
    [blue] => available
    [green] => available
  )

  [shoes] => Array
  (
    [red] => available
    [blue] => available
    [green] => available
  )

  [pants] => Array
  (
    [red] => available
    [blue] => available
    [green] => available
  )
)

However, it appears to be only returning the last item in the second array...

Array
(
  [shirt] => Array
  (
    [green] => available
  )

  [shoes] => Array
  (
    [green] => available
  )

  [pants] => Array
  (
    [green] => available
  )
)

Here is the full code. Basically you are defining a new array each time you loop through the colors, replacing the previous.

function stuff() 
{
  $items = array('shirt', 'shoes', 'pants');
  $colors = array('red', 'blue', 'green');
  $list = array();
  foreach($items as $item) 
  {
      foreach($colors as $color) 
      {
         $list[$item][$color] = 'available';
      }
  }
 return $list;
}

print_r(stuff());

replace

 $list[$item] = array($color => 'available');

with

 $list[$item][$color] = 'available';

Change $list[$item] = array($color => 'available'); to $list[$item][$color] = 'available'; and your problem will be solved.
