排序有什么更好的步骤

排序有什么更好的方法
array(
[0] =>array(
 'name' => "a",
 'time' => '879798'),
[1] = >array(
 'name' => "a9",
 'time' => '85665565'),
[2] = >array(
 'name' => "hdhdjd",
 'time' => '8154465'),
[3] = >array(
 'name' => "a",
 'time' => '800000'),
[4] = >array(
 'name' => "dr",
 'time' => '789898'),
);


是一个已经按照time排序好的数组
现在要排这样

array(
[0] =>array(
'name' => "a",
'time' => '879798'),
[1] = >array(
'name' => "a",
'time' => '800000'),
[2] = >array(
 'name' => "a9",
 'time' => '85665565'),
[3] = >array(
 'name' => "hdhdjd",
 'time' => '8154465'),

[4] = >array(
 'name' => "dr",
 'time' => '789898'),
);

把name相同的在一起。以第一个出现的次序为大。

不知道有什么好方式啊，代码写的漂亮点的。

------解决方案--------------------

PHP code

$ar = array(
0 =>array(
 'name' => "a",
 'time' => '879798'),
1 => array(
 'name' => "a9",
 'time' => '856565'), //85665565 ? 示例数据有问题吧，看不出是按time排序的！
2 =>array(
 'name' => "hdhdjd",
 'time' => '815465'),
3 =>array(
 'name' => "a",
 'time' => '800000'),
4 =>array(
 'name' => "dr",
 'time' => '789898'),
);

$result = array();
$len = count($ar);
for ($i = 0; $i ';
print_r($result);
