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。
