Php 按日期对多维数组排序

我有一个数组[all_comments]，其中包含3个数组-[title]、[content]和[date]

我想按[日期]对[所有评论]进行排序。我在这个论坛上尝试了很多日期比较功能，但似乎没有什么对我有用。感激地接受任何帮助或建议-谢谢

以下是我一直在尝试的函数类型：

function date_compare($a, $b)
{
    $t1 = strtotime($a['date']);
    $t2 = strtotime($b['date']);
    return $t1 - $t2;
} 

这就是我的阵列的外观：

[all_comments] = Array 
( 
    [title] => Array 
    ( 
    [0] => bis posted an update in the group Strategic Resourcing
    [1] => bis posted a new activity comment 
    [2] => bis posted a new activity comment 
    [3] => bis posted an update 
    [4] => bis posted an update in the group Managing for Performance 
    ) 

    [content] => Array 
    ( 
    [0] => @david hey david the meeting earlier was very interesting - thanks! 
    [1] => Strategic Resourcing & Onboarding description.
    [2] => And another one to the original reply 
    [3] => This is a sample reply. 
    [4] => This is a new entry - does it go to the forum? 
    ) 

    [date] => Array 
    ( 
    [0] => 13-11-2013 5:36:48
    [1] => 24-10-2013 9:52:48 
    [2] => 12-11-2013 12:40:46
    [3] => 14-11-2013 2:26:04 
    [4] => 13-11-2013 5:39:49

    ) 
)

这就是我调用函数的方式：

usort($all_comments,"date_compare");

这就是我打印阵列的方式：

        for($k=0;$k<count($all_comments ['title']);$k++){
        echo ($all_comments ['title'][$k]) . "<br />"; 
        echo ($all_comments ['content'][$k]) . "<br />"; 
        echo ($all_comments ['date'][$k]) . "<br /><br />"; 
        echo "<br />"; 
        }

答案更新： 数组的结构不正确。首先对其进行以下修改：

<?php
$all_comments = array
( 
    "title" => array 
    ( 
    0 => "bis posted an update in the group Strategic Resourcing",
    1 => "bis posted a new activity comment",
    2 => "bis posted a new activity comment",
    3 => "bis posted an update",
    4 => "bis posted an update in the group Managing for Performance",
    ),

    "content" => Array 
    ( 
    0 => "@david hey david the meeting earlier was very interesting - thanks!",
    1 => "Strategic Resourcing & Onboarding description.",
    2 => "And another one to the original reply",
    3 => "This is a sample reply.",
    4 => "This is a new entry - does it go to the forum?",
    ),

    "date" => Array 
    ( 
    0 => "13-11-2013 5:36:48",
    1 => "24-10-2013 9:52:48",
    2 => "12-11-2013 12:40:46",
    3 => "14-11-2013 2:26:04",
    4 => "13-11-2013 5:39:49",

    ),
);

$newArr = array();
foreach($all_comments as $masterKey => $masterValue) {
    foreach ($masterValue as $key => $value) {
      $newArr[$key][$masterKey] = $value;
    }
}

var_dump($newArr);

非常感谢您优雅的解决方案，并为我迟来的回复道歉。我通过首先合并标题、内容和日期数组找到了解决方案。然后，日期排序功能开始工作，我能够打印出合并数组中每个I元素的标题、日期和内容元素。@BiswadipDasgupta Welcome:）别忘了接受答案
