PHP 两个时间差 自动返回多少天之前 

 1 function nicetime($date)
 2 {
 3     if(empty($date)) {
 4         return "No date provided";
 5     }
 6 
 7     $periods         = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
 8     $lengths         = array("60","60","24","7","4.35","12","10");
 9 
10     $now             = time();
11     $unix_date         = strtotime($date);
12 
13        // check validity of date
14     if(empty($unix_date)) {    
15         return "Bad date";
16     }
17     // is it future date or past date
18     if($now > $unix_date) {    
19         $difference     = $now - $unix_date;
20         $tense         = "ago";
21 
22     } else {
23         $difference     = $unix_date - $now;
24         $tense         = "from now";
25     }
26 
27     for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
28         $difference /= $lengths[$j];
29     }
30 
31     $difference = round($difference);
32 
33     if($difference != 1) {
34         $periods[$j].= "s";
35     }
36 
37     return "$difference $periods[$j] {$tense}";
38 }

使用上面函数即可  需要需要一下返回的信息

 

<?php
$date = "2016-05-06 03:45";
$result = nicetime($date); // 1 days ago
