Question

我需要使用Date＆amp; amp;按升序对此数组进行排序。时间，我要排序的数组如下： -

Array ( 
    [0] => 005
    [1] => 2011-09-12 12:28:46 
    [2] => IN 
    [3] => GATE1 
    [4] => NULL 
) 

Array (
     [0] => 003 
     [1] => 2011-09-12 12:23:43 
     [2] => IN 
     [3] => GATE1
     [4] => NULL 
)

Array (
    [0] => 001
    [1] => 2011-09-12 12:23:37
    [2] => IN
    [3] => GATE1
    [4] => NULL 
) 

Array ( 
    [0] => 002 
    [1] => 2011-09-12 12:23:34
    [2] => IN 
    [3] => GATE1 
    [4] => NULL 
)

Array ( 
    [0] => 012 
    [1] => 2011-09-12 12:23:29
    [2] => OUT 
    [3] => GATE1
    [4] => NULL 
)

Array ( 
    [0] => 010 
    [1] => 2011-09-12 12:23:25 
    [2] => OUT 
    [3] => GATE1 
    [4] => NULL 
)

使用usort：

usort($array, function($a, $b) {
    return strcmp($a[1], $b[1]);
});

或者使用PHP＆lt; 5.3：

function sort_cb($a, $b) {
    return strcmp($a[1], $b[1]);
}
usort($array, 'sort_cb');

在此处试试：http://codepad.org/J8U2G32A

或者，array_multisort：

$dates = array_map(function($a) { return $a[1]; }, $array);
array_multisort($array, $dates);

在PHP中对数组中的日期和时间进行排序
