Facebook API PHP - 发布“created_time”数据未正确显示

Question

我正在使用 PHP 制作 Facebook 应用程序。通过 Facebook API，应用程序显示登录用户的最新帖子。在检索每个帖子的created_time 时，我发现它要么没有显示任何内容，要么只显示1970-01-01T00:00:00+0000。 （这可以在下图中看到。）即使我使用DateTime，它仍然存在。

它应该返回类似2016-01-31T16:31:26+0000 的内容，如使用 Facebook 的 Graph API Explorer 所见。

不知道如何纠正这个问题，我能够让它以正确的格式显示，如下所示：

$ts = strtotime($key['created_time']);
$myTime = gmdate(DATE_ISO8601, $ts);

所有信息均来自 Facebook，并位于 foreach 循环中。它遍历每个帖子并知道将什么放在哪里，并且每个created_time 值都被满足为$key['created_time']

这是我的代码：

<?php

    // Getting all posts published by user
    try {
        $posts_request = $fb->get('/me/posts?fields=id,created_time,message,link,picture,name&limit=7');
        $posts_response = $posts_request->getGraphEdge();
    } catch(Facebook\Exceptions\FacebookResponseException $e) {
        // When Graph returns an error
        echo 'Graph returned an error: ' . $e->getMessage();
        exit;
    } catch(Facebook\Exceptions\FacebookSDKException $e) {
        // When validation fails or other local issues
        echo 'Facebook SDK returned an error: ' . $e->getMessage();
        exit;
    }


    if ($fb->next($posts_response))  {
        $total_posts = $posts_response->asArray();
        $totalPosts = count($total_posts);

        // Form - Post
            echo "<p><strong>* With this text box below, you can post to your Facebook Profile about your experience using this application if you wish. Once submitted, this post will then also appear in the list of your other posts below.</strong></p>";
            echo "<form action='posttouserstimeline.php' method='post'>";
            echo "<textarea name='description' class='posts'></textarea>";
            echo "<br><br>";
            echo "<input type='submit' class='webbutton' value='Post to Facebook'>";
            echo "</form>";
            echo "<br>";
            echo "<p><strong>* Below are your '5' most resent posts, from your Facebook Profile</strong></p>";

            //$date = new DateTime($key['created_time']);

        foreach($total_posts as $key) {

            $ts = strtotime($key['created_time']);
            $myTime = gmdate(DATE_ISO8601, $ts);

            echo "Time and Date of Post: ".$myTime."<br>";
            echo "<img class='postsprofile' alt='profilepic' src='".$picture['url']."'/> <a href='https://facebook.com/".$profile['id']."' target='_blank'>".$profile['name']."</a><br>";
            echo $key['message'].'<br><br>';
             echo "<a href='".$key['link']."' target='_blank'><img class='postsprofile' alt='".$key['name']."' src='".$key['picture']."'/></a><br><hr><br>";

            //echo "<img class='postsprofile' alt='".$key['name']."' src='".$key['picture']."'/><br>";
            //echo "<a href='".$key['link']."' target='_blank'>".$key['link']."</a><br><hr><br>";
        }
    }

问题是 facebook 时间函数没有给出从 strtotime 调用工作所需的标准数字形式的时间。这是我在网上找到的一个函数，可以将 facebook 时间转换为我们习惯的标准数字形式的时间。

var fuzzyFacebookTime = (function(){

  fuzzyTime.defaultOptions={
    // time display options
    relativeTime : 48,
    // language options
    monthNames : ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
    amPm : ['AM', 'PM'],
    ordinalSuffix : function(n) {return ['th','st','nd','rd'][n<4 || (n>20 && n % 10<4) ? n % 10 : 0]}
  }

  function fuzzyTime (timeValue, options) {

    var options=options||fuzzyTime.defaultOptions, 
        date=parseDate(timeValue),
        delta=parseInt(((new Date()).getTime()-date.getTime())/1000),
        relative=options.relativeTime,
        cutoff=+relative===relative ? relative*60*60 : Infinity;

    if (relative===false || delta>cutoff)
      return formatTime(date, options)+' '+formatDate(date, options);

    if (delta<60) return 'less than a minute ago';
    var minutes=parseInt(delta/60 +0.5);
    if (minutes <= 1) return 'about a minute ago';
    var hours=parseInt(minutes/60 +0.5);
    if (hours<1) return minutes+' minutes ago';
    if (hours==1) return 'about an hour ago';
    var days=parseInt(hours/24 +0.5);
    if (days<1) return hours+' hours ago';
    if (days==1) return formatTime(date, options)+' yesterday';
    var weeks=parseInt(days/7 +0.5);
    if (weeks<2) return formatTime(date, options)+' '+days+' days ago';
    var months=parseInt(weeks/4.34812141 +0.5);
    if (months<2) return weeks+' weeks ago';
    var years=parseInt(months/12 +0.5);
    if (years<2) return months+' months ago';
    return years+' years ago';
  }

  function parseDate (str) {
    var v=str.replace(/[T\+]/g,' ').split(' ');
    return new Date(Date.parse(v[0] + " " + v[1] + " UTC"));
  }

  function formatTime (date, options) {
    var h=date.getHours(), m=''+date.getMinutes(), am=options.amPm;
    return (h>12 ? h-12 : h)+':'+(m.length==1 ? '0' : '' )+m+' '+(h<12 ? am[0] : am[1]);
  }

  function formatDate (date, options) {
    var mon=options.monthNames[date.getMonth()],
        day=date.getDate(),
        year=date.getFullYear(),
        thisyear=(new Date()).getFullYear(),
        suf=options.ordinalSuffix(day);

    return mon+' '+day+suf+(thisyear!=year ? ', '+year : '');
  }

  return fuzzyTime;

}());
