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, $format = 'g:i A M jS') {
 if (empty($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。
