如果日期在今天或之前，我该如何解决？ [英] How can I work out if a date is on or before today?

问题描述

我的网页应用程序包含图书馆类型系统，书籍有到期日期。

我的网页上显示了当前日期，只需使用以下内容：

  date_default_timezone_set（'Europe / London'）; 
 
 $ date = date; 
打印$ date（d / m / Y）; 
  

我将'date'设置为变量，因为我不知道是否有所作为我在图书馆图书页面的IF声明中使用它。

在这个页面上，我只是输出这些书的到期日，许多有日期尚未到达日期，其他日期大于今天的日期。
基本上，我想要的是到期日期显示为粗体（或强），如果它已经过去今天的日期（系统显示日期）。这是我所想的，并认为会奏效：

  < 
 if（$ duedate< $ date）{
 echo'< td>< strong>'; 
} else {
 echo'< td>'; 
}？> 
 
<？php echo $ date（'d / m / Y'，$ timestamp）;？>< / strong>< / td> 
  

我已将$ timestamp声明为var，将默认MySQL格式的日期转换为英文版。谁能帮我吗？我以为这是非常直接的！

解决方案

尝试：

  if（strtotime（$ duedate）< time（））{
 // oooh，你的书迟了！ 
} 
  

My web application consists of library type system where books have due dates.

I have the current date displayed on my page, simply by using this:

date_default_timezone_set('Europe/London');

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

I have set 'date' as a variable because I'm not sure if it makes a difference when I use it in the IF statement you're about see, on my library books page.

On this page, I am simply outputting the due dates of the books, many have dates which have not yet reached todays date, and others which have dates greater than todays date. Basically, all I want is the due date to appear bold (or strong), if it has passed todays date (the system displayed date). This is what I have and thought would work:

<?
if ($duedate < $date) {
  echo '<td><strong>';
} else {
  echo '<td>';
} ?>

<?php echo $date('d/m/Y', $timestamp);?></strong></td>

I have declared $timestamp as a var which converts the date of default MySQL format to a UK version. Can anyone help me out? I thought this would've been very straight forward!

解决方案

try:

if (strtotime($duedate) < time()) {
    // oooh, your book is late!
}
