在PHP之前，如何检查操作是否发生在最近5天之前？ [英] How do I check to see if action occurred up to 5 days before today in PHP?

问题描述

我正在开发一个功能来查看是否在今天的最近5天内发送短信。我已经可以检查今天是否发送了（见下文），但是我早在5天前就已经遇到了困难。

I'm working on a function to see if an SMS was sent within the last 5 days of 'today'. I can already check if it's been sent today (see below) but I'm struggling with the up to 5 days earlier part.

// Check if SMS already sent today
        if ($this->sms_sent == $today->format('Y-m-d'))
        {
            return true;
        }

我需要知道短信是否在5天前发送。 / p>

I need to know if the SMS was sent up to 5 days ago.

推荐答案

使用此

    $now=date('Y-m-d');
    $days_ago = date('Y-m-d', strtotime('-5 days', strtotime($now )));//get five days before date
    if($this->sms_sent <= $now && $this->sms_sent >= $days_ago) {
        // It's between
    }
