php 配列

このような配列があります:

Array(    [0] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 39.9289            [longitude] => 116.3883        )    [1] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 42            [longitude] => 43.5        )    [2] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 38.9122            [longitude] => 121.6022        )    [3] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 40.5525            [longitude] => -74.2915        )    [4] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 40.5525            [longitude] => -74.2915        )    [5] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 38.9122            [longitude] => 121.6022        )    [6] => Array        (            [time] => 1382060855000            [day] => 2013-10-18            [latitude] => 38.9122            [longitude] => 121.6022        ))

経度と緯度に重複したデータがあります。重複したデータを除外して、それぞれ同じ経度と緯度の番号を取得したいです。取得された最終的な配列は次のとおりです:


これを実装するにはどうすればよいですか?讨 ディスカッションへの返信 (解決策)

array
(
[0] = & gt; array
(
[緯度] = & gt; 39.9289
[経度] = & gt; 116.3883
[カウント] = >. 1
)


[緯度] => 38.9122
[経度] => 121.6022
[カウント] => 3
)
[3] => 配列
(
[緯度] =＆gt;
