本文实例讲述了php输出指定时间以前时间格式的方法。分享给大家供大家参考。具体分析如下:

比如说你需要在php中输出3天前,20分钟以前,可以参考下面的代码

function ago($time) {
 $time = strtotime($time);
 $delta = time() - $time;
 if ($delta < 60) {
  return 'less than a minute ago.';
 } else if ($delta < 120) {
  return 'about a minute ago.';
 } else if ($delta < (45 * 60)) {
  return floor($delta / 60) . ' minutes ago.';
 } else if ($delta < (90 * 60)) {
  return 'about an hour ago.';
 } else if ($delta < (24 * 60 * 60)) {
  return 'about ' . floor($delta / 3600) . ' hour(s) ago.';
 } else if ($delta < (48 * 60 * 60)) {
  return '1 day ago.';
 } else {
  return floor($delta / 86400) . ' days ago.';
 }
}
Copy after login

希望本文所述对大家的php程序设计有所帮助。
