PHP排序內蒙古，內蒙古陣列

Question

好吧，我有一個這樣的數組：

array { 
    [0] => array { 
       [0] => array { 
         ["Time"] => "01:00:00" 
         } 
       [1] => array { 
         ["Time"] => "00:00:00" 
         } 
    } 
    [1] => array { 
       [0] => array { 
         ["Time"] => "01:00:00" 
         } 
       [1] => array { 
         ["Time"] => "00:00:00" 
         } 
    } 
} 

現在我想要做的就是那種裏面的內陣列（一個與時間值）的時間值。只是爲了讓內部數組按時間值排序。我將如何做到這一點？

我確實安裝了PHP 5.3，如果這是有幫助的。

Answer 1

function custom_map($array) { 
    usort($array, function($a, $b) { 
     return strtotime($a['Time'])-strtotime($b['Time']) > 0; 
    }); 
    return $array; 
} 

$new_array = array_map("custom_map", $array);

試試這個：

$arr = array(array(array("Time" => "01:00:00"), array("Time" => "02:00:00"), array("Time" => "00:00:00")), 
      array(array("Time" => "02:00:00"), array("Time" => "01:00:00"), array("Time" => "00:00:00"))); 

$c = count($arr); 
for ($i = 0; $i < $c; $i++) { 
    sort($arr[$i]); 
} 

var_dump($arr); // outputs desired array 

Answer 3

foreach ($array as $key => &$part) 
{ 
    usort(&$part, function($a, $b) { 
     return strtotime($a['Time'])-strtotime($b['Time']) > 0; 
    }); 
}
