php - 计算一个月的剩余天数

Question

假设我有一个用户可以选择一个月中的某个日期。比方说，如果他选择 2014 年 10 月 16 日，我想将该月的剩余天数显示为日历。

<?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; 
}

到目前为止，代码非常困惑。我只是没有办法绕过这个，这就是我问的原因。

Answer 1

您可以使用 strtotime和 date .

对于 date 的格式，您可以使用以下格式:

't' Number of days in the given month (28 through 31)
'j' Day of the month without leading zeros (1 to 31)

<?php

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

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

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

编辑:显然您想列出该月的剩余天数:

<?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);
}
