如何按日期排序此數組？

Question

我試圖解決這類型的數組：

array (
    0 => 
    array (
    'id_ouverture' => 5, 
    'debut' => '2011-04-25 08:00:00', 
    'fin' => '2011-04-25 20:00:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
), 
    1 => 
    array (
    'id_ouverture' => 6, 
    'debut' => '2011-04-18 08:00:00', 
    'fin' => '2011-04-18 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
), 
    2 => 
    array (
    'id_ouverture' => 7, 
    'debut' => '2011-05-02 08:00:00', 
    'fin' => '2011-05-02 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1, 
    ), 
), 
    3 => 
    array (
    'id_ouverture' => 8, 
    'debut' => '2011-05-09 08:00:00', 
    'fin' => '2011-05-09 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
)); 

我需要排序這個鍵在這個數組：數組[$ i] [「處女作」]升序排列的。

結果必然是：

array (
    1 => 
    array (
    'id_ouverture' => 6, 
    'debut' => '2011-04-18 08:00:00', 
    'fin' => '2011-04-18 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
), 
    0 => 
    array (
    'id_ouverture' => 5, 
    'debut' => '2011-04-25 08:00:00', 
    'fin' => '2011-04-25 20:00:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
), 

    2 => 
    array (
    'id_ouverture' => 7, 
    'debut' => '2011-05-02 08:00:00', 
    'fin' => '2011-05-02 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1, 
    ), 
), 
    3 => 
    array (
    'id_ouverture' => 8, 
    'debut' => '2011-05-09 08:00:00', 
    'fin' => '2011-05-09 10:45:00', 
    'id_salle' => 
    array(
     'id' => '7', 
     'nom' => 'BLABLA', 
     'id_type_salle' => '3', 
     'visible' => 1,   
    ), 
)); 

你有一個想法，辦呢？

Answer 1

您需要使用uasort來編寫一個函數來爲您排序數組。

基本上你寫你自己的比較函數，並把它作爲一個回調到uasort方法
