这篇文章主要介绍了php实现求相对时间函数,可实现简单求相对时间为几分钟前或几小时前的功能,非常简单实用,需要的朋友可以参考下
本文实例讲述了php实现求相对时间函数。分享给大家供大家参考。具体实现方法如下:
- <?php
- function relativeTime($time = false, $limit = 86400, $format = 'g:i A M jS') {
- if (emptyempty($time) || (!is_string($time) & amp; & amp;
- !is_numeric($time))) $time = time();
- elseif (is_string($time)) $time = strtotime($time);
- $now = time();
- $relative = '';
- if ($time === $now) $relative = 'now';
- elseif ($time > $now) $relative = 'in the future';
- else {
- $diff = $now - $time;
- if ($diff >= $limit) $relative = date($format, $time);
- elseif ($diff < 60) {
- $relative = 'less than one minute ago';
- } elseif (($minutes = ceil($diff / 60)) < 60) {
- $relative = $minutes . ' minute' . (((int)$minutes === 1) ? '' : 's') . ' ago';
- } else {
- $hours = ceil($diff / 3600);
- $relative = 'about ' . $hours . ' hour' . (((int)$hours === 1) ? '' : 's') . ' ago';
- }
- }
- return $relative;
- }
希望本文所述对大家的php程序设计有所帮助。
