Question

假设我有一个能够选择当月某个日期的用户。如果他愿意，让我们说，选择2014年10月16日，我想将该月的剩余日期显示为日历。

<?php
error_reporting(0);

$data  = $_POST['input'];
$days = array('Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday');

$m = date('m'); $y = date('y');
$d = cal_days_in_month(CAL_GREGORIAN,$m,$y);

for ($i=1;$i<;$i++){ 
    echo $i + 1; 
}

截至目前，代码非常混乱。我只是没办法绕过这个，这就是我问的原因。

Answer 1

您可以使用strtotime和date。

对于date的格式，您可以使用以下内容：

't' 指定月份的天数（ 28到31 ）
'j' 没有前导零的月份（ 1到31 ）

<?php

$timestamp = strtotime('2014-10-03');

$daysRemaining = (int)date('t', $timestamp) - (int)date('j', $timestamp);

var_dump($daysRemaining); // int(28)

修改：显然您想列出当月的剩余天数：

<?php

$timestamp = strtotime('2014-10-03');
$yearMonth = date('Y-m-', $timestamp);

$daysInMonth = (int)date('t', $timestamp);

for ($i = (int)date('j', $timestamp); $i <= $daysInMonth; $i++) {
    $dateString = date('l \t\h\e jS \o\f F', strtotime($yearMonth . $i));

    var_dump($dateString);
}

Answer 2

为什么你这么复杂，使用日期（＆＃39; t＆＃39;）来获取你可以做的月份天数，例如：

echo date('t') - date('j');

将计算当月的剩余天数。

如果您想从特定日期开始剩余天数

$date = strtotime($_POST['input']);
echo date('t', $date) - date('j', $date);

计算一个月的剩余天数
