按特定级别索引重新排列数组顺序

Question

I have been searching this but did not find any solution anywhere. I want to re order my array with a specific index.

Like this:

$scoreboard = array(
    'foo' => array(
        'score' => 580,
        'game' => 'google',
    ),
    'bar' => array(
        'score' => 1385,
        'game' => 'facebook',
    ),
    'car' => array(
        'score' => 750,
        'game' => 'tweet',
    ),
);

And the output should be like this:

$scoreboard = array(
    'bar' => array(
        'score' => 1385,
        'game' => 'facebook',
    ),
    'car' => array(
        'score' => 750,
        'game' => 'tweet',
    ),
    'foo' => array(
        'score' => 580,
        'game' => 'google',
    ),
);

See that the array is rearranged with each item's 'score' index. Any help here?

Expanding on on my comment where I suggested to use the uasort function, here is a working sample: http://codepad.org/fBSqHNCC
