在php中,可以使用strtotime()函数获取几天后的时间戳。

strtotime() 函数有两种用法:一种是将字符串形式的、用英文文本描述的日期时间解析为 UNIX 时间戳,一种是用来计算一些日期时间的间隔。

php 获取几天后的时间戳可以使用以下语句:

<?php
header("Content-type:text/html;charset=utf-8");
$d=strtotime(&#39;+10 day&#39;);//获取10天后的时间戳
echo $d."<br><br>"; 
$t=date("Y-m-d h:i:s",$d);
echo "获取的时间戳代表: ".$t;
?>

使用strtotime() 函数进行日期的加减运算

有时我们需要在一个日期上加减一定的时间间隔。可以使用 strtotime() 来计算一些日期时间间隔。示例如下:

<?php
header("Content-type:text/html;charset=utf-8");
$start = &#39;last Monday&#39;;
$interval = strtotime("$start + 4 days");
echo "现在\$interval 表示上周的" . date(&#39;l&#39;,$interval);
?>
Copy after login

执行以上程序的输出结果为:

如果日期使用时间戳表示,并且时间间隔也可用秒来表示,就可以从时间戳中减去时间间隔。示例如下;

<?php
header("Content-type:text/html;charset=utf-8");
$start = time();
echo date(&#39;Y-m-d&#39;,$start) , "<br />";
$interval = 7 * 24 * 3600;  //一周
$end = $start - $interval;
echo date(&#39;Y-m-d&#39;,$end);
?>
Copy after login

执行以上程序的输出结果为:
