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;
    $str = &#39;&#39;;
    if ($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;
  }

        if($m == 0) {
