Question

我有一项任务是创建活动供稿视图，例如https://dribbble.com/shots/1434168-Assembly-Activity-Stream/attachments/211032。

我想将小组中的笔记/帖子分组，例如“小时前”，“小时前”，“小时”，“等等”和“等等”。在页面上显示它。（就像在图像中一样）例如我的数组看起来像：

$data = array(
    array(
            'id' => 1,
            'msg' => '...',
            'created_at' => timestamp
        ),
    array(
            'id' => 2,
            'msg' => '...',
            'created_at' => timestamp
        ),
    ...
    ...
);

这样做的最佳解决方案是什么？

Answer 1

您可以创建一个功能：

function dateDifference($first,$last){
    $hourdiff = round((strtotime($last) - strtotime($first))/3600);
    return $hourdiff;
}

$dt1= "2015-06-05 11:07:23";
$dt2= date("Y-m-d H:i:s");
echo dateDifference($dt1,$dt2);

Answer 2

使用Carbon

示例：

echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

Answer 3

imo，您应该获取created_at DESC所订购的数据，然后在循环浏览数组时将之前的时间戳与当前（在循环中）进行比较，如果超过1小时的差异，它应该去在另一组。

我正在使用Laravel 4.2中提供的Carbon。

一个基本的例子（我相信我并未涵盖所有案例，但它是一个开始。留下一些评论和调试消息以便清除：

$activityPosts = [
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 20:00'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 19:37'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 19:29'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 19:13'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 18:25'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 18:01'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 13:56'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 12:18'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 12:05'),
    ],
    [
        'id' => null,
        'msg' => 'Message #',
        'created_at' => strtotime('yesterday 10:28'),
    ]
];
$activityPosts = array_reverse($activityPosts); //I just built the array wrong (Im not a smart girl...)
echo '<div style="border: 1px solid red; width: 250px; margin-bottom: 5px">';
foreach ($activityPosts as $k => $post) {
    $getHour = \Carbon\Carbon::createFromTimeStamp($post['created_at'])->hour;
    if (isset($activityPosts[$k - 1])) {
        $prevHour = \Carbon\Carbon::createFromTimeStamp($activityPosts[$k - 1]['created_at'])->hour;
        if ($getHour !== $prevHour) {
            echo '</div>';
            echo '<div style="border: 1px solid red; width: 250px;margin-bottom: 5px">';
        }
        echo '<hr />';
        echo 'Current: ' . $getHour . 'h Prev:' . $prevHour . 'h';
        echo '<hr />';
    }
    echo "<h4>Message: {$post['msg']}{$k}</h4>";
    echo $post['created_at'];
    echo '<h4>' . \Carbon\Carbon::createFromTimeStamp($post['created_at'])->diffForHumans() . '</h4>';
}
echo '</div>';

按时间分组并显示它们
