Searching multi-dimensional arrays

[Anon]

I can't seem to figure this one out.

I have a 2D array set up something like so:

$silly = array (
array ( name=>"things", other=>"stuff" ),
array ( name=>"unthings", other=>"beep")
);

So lets say that later, I have access to $silly and I know I want all the information associated with whichever array has the name "unthings." I don't know where it is inside of $silly (pretend there's a billion arrays in there). Is there an efficient way to get the information without doing something silly like a for loop?

<?
foreach ($silly as $key => $value)
{
if ($value['name'] == 'unthings')
{
echo "Found unthings in key number $key\n";
}
}
?>
