Detailed explanation of php formatted timestamp graphic and text

Generally, Unix timestamps are used to store time in mysql database. So what if it is more friendly when we display the time? Today I will share with you 3 encapsulated formatting functions. Friends in need can refer to it. Next

Generally, articles with a relatively new display time in CMS need to be displayed a few minutes ago, a few days ago, but generally the database records are timestamps (at least I am used to this), so a conversion is needed In the process, I encapsulated two pieces of code based on the information on the Internet and my own modifications

The following is the encapsulated method

function formatTime($time) {
    $time = (int) substr($time, 0, 10);
    $int = time() - $time;
    $str = '';
    if ($int <= 2){
      $str = sprintf(&#39;刚刚&#39;, $int);
    }elseif ($int < 60){
      $str = sprintf(&#39;%d秒前&#39;, $int);
    }elseif ($int < 3600){
      $str = sprintf(&#39;%d分钟前&#39;, floor($int / 60));
    }elseif ($int < 86400){
      $str = sprintf(&#39;%d小时前&#39;, floor($int / 3600));
    }elseif ($int < 2592000){
      $str = sprintf(&#39;%d天前&#39;, floor($int / 86400));
    }else{
      $str = date(&#39;Y-m-d H:i:s&#39;, $time);
    }
    return $str;
  }

Or more detailed

  function formatTime($time)
  {
    $text = '';
    $time = intval($time);
    $ctime = time();
    $t = $ctime - $time; //时间差
    if ($t < 0) {
      return date(&#39;Y-m-d&#39;, $time);
    }
    ;
    $y = date(&#39;Y&#39;, $ctime) - date(&#39;Y&#39;, $time);//是否跨年
    switch ($t) {
      case $t == 0:
        $text = &#39;刚刚&#39;;
        break;
      case $t < 60://一分钟内
        $text = $t . &#39;秒前&#39;;
        break;
      case $t < 3600://一小时内
        $text = floor($t / 60) . &#39;分钟前&#39;;
        break;
      case $t < 86400://一天内
        $text = floor($t / 3600) . &#39;小时前&#39;; // 一天内
        break;
      case $t < 2592000://30天内
        if($time > strtotime(date(&#39;Ymd&#39;,strtotime("-1 day")))) {
          $text = &#39;昨天&#39;;
        } elseif($time > strtotime(date(&#39;Ymd&#39;,strtotime("-2 days")))) {
          $text = &#39;前天&#39;;
        } else {
          $text = floor($t / 86400) . &#39;天前&#39;;
        }
        break;
      case $t < 31536000 && $y == 0://一年内 不跨年
        $m = date(&#39;m&#39;, $ctime) - date(&#39;m&#39;, $time) -1;

        if($m == 0) {
          $text = floor($t / 86400) . &#39;天前&#39;;
        } else {
          $text = $m . &#39;个月前&#39;;
        }
        break;
      case $t < 31536000 && $y > 0://一年内 跨年
        $text = (11 - date(&#39;m&#39;, $time) + date(&#39;m&#39;, $ctime)) . &#39;个月前&#39;;
        break;
      default:
        $text = (date(&#39;Y&#39;, $ctime) - date(&#39;Y&#39;, $time)) . &#39;年前&#39;;
        break;
    }

    return $text;
  }
