数组排序问题急！

[vv452]

我有个二维数组：

$a = array(
[0] = {
`name`=> 'ZhangSan',
`score`=> 90
}
[1] = {
`name`=> 'CangFan',
`score`=> 70
}
[2] = {
`name`=> 'GngPan',
`score`=> 80
}
[3] = {
`name`=> 'LiGang',
`score`=> 60
}
)

按score从小到大 将这个数组重新排一下。 例如变成：

$a = array(
[0] = {
`name`=> 'LiGang',
`score`=> 60
}
[1] = {
`name`=> 'CangFan',
`score`=> 70
}
[2] = {
`name`=> 'GngPan',
`score`=> 80
}
[3] = {
`name`=> 'ZhangSan',
`score`=> 90
}

)

顶，uasort可以自定义比较函数

$a = array(
  0 => array(
  "name"=> 'ZhangSan',
  "score"=> 90
  ),
  1 => array(
  "name"=> 'CangFan',
  "score"=> 70
  ),
  2 => array(
  "name"=> 'GngPan',
  "score"=> 80
  ),
  3 => array(
  "name"=> 'LiGang',
  "score"=> 60
  )
);
function mysort($i,$j)
{
	if($i["score"] == $j["score"])
	{
		return 0;
	}
	return ($i["score"] > $j["score"]) ? 1 : -1;

}
uasort($a,"mysort");
echo "<pre>";
print_r($a);
echo "</pre>";

function cmp ($a, $b) {
if ($a['score'] == $b['score']) return 0;
return ($a['score'] < $b['score']) ? -1 : 1;
}
$a = array(
array("name"=> 'ZhangSan',"score"=> 90),
array("name"=> 'CangFan',"score"=> 70),
array("name"=> 'GngPan',"score"=> 80),
array("name"=> 'LiGang',"score"=> 60)
);

usort ($a, "cmp");
print_r($a);die;

这样？？
