我正在尝试对此类数组进行排序：

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,           
    ),
  ));

我需要根据这个键对这个数组进行排序：array[$i]['debut'] 按升序排列。

结果必须是：

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,           
    ),
  ));

你有想法吗？

【解决方案1】：

您需要使用uasort 编写一个函数来为您排序数组。

基本上你编写自己的比较函数并将其作为回调传递给uasort 方法
