我想使用一个函数来输出日期范围内的天数
为此,我使用类似下面的内容;
~/Documents/ElectoralRollPDFs/completed/Baharagora/*.pdf
I/O Error: Couldn't open file '~/Documents/ElectoralRollPDFs/completed/Baharagora/*.pdf': No such file or directory.
但是,当我退出$from = $_POST['from'];
$to = $_POST['to'];
$numdays = date_diff($to,$from);
时,它始终为“ 0”。我该如何正确处理?
任何线索?

您必须将字符串转换为日期格式以进行计算,然后再转换回字符串以显示它
<?php
if(isset($_POST['from']) && isset($_POST['to'])){
$from = date_create($_POST['from']);
$to = date_create($_POST['to']);
$numdays = date_diff($from,$to);
echo $numdays->format("%r%a days");
}
?>
<form action="" method="post">
<lable for="from">from</lable>
<input type="date" name="from" id="from">
<lable for="to">to</lable>
<input type="date" name="to" id="to">
<input type="submit">

首先使用date_create为日期创建日期对象,然后计算差异为:
$numdays = date_diff(date_create($_POST['from']), date_create($_POST['to']))->format('%a');
详细了解date_diff。
