PHP 检查今天是否在两个日期之间

PHP check if today is in between two dates

考虑以下代码:

$today = date("d/m/Y");

$start_date = '20/11/2014';
$time1 = strtotime($start_date1);
$start_date1 = date('d/m/Y',$time1);

$end_date = '20/01/2015';
$time2 = strtotime($end_date1);
$end_date1 = date('d/m/Y',$time2);

if( $start_date1 <= $today && $end_date1 >= $today)
    echo "yes";
else
    echo 'no';

即使 $today 在开始日期和结束日期之间,我在 return 中得到 "no"。这可能是什么问题?我只想检查今天是否在这些日期之间。开始日期和结束日期在数据库中保存为字符串。

试试这个:

<?php

    $now = new DateTime();
    $startdate = new DateTime("2014-11-20");
    $enddate = new DateTime("2015-01-20");

    if($startdate <= $now && $now <= $enddate) {
        echo "Yes";
    }else{
        echo "No";
    }

?>
