无法删除PHP中的$ _COOKIE返回的编码（在MAMP服务器上）

Question

I finally got cookies to work only for my output to display like this:

You last requested an internship opportunity on Wednesday%2C+November+15%2C+2017%2C+3%3A+33+AM.

I have tried using urldecode(),rawurldecode(), setrawcookie(), implode(), and explode(). None of these have had any affect on the output, and I haven't seen other suggestions in similar questions. If anyone has an idea of what might work, I would appreciate the information.

Below I have included some of the code (there's two files involved so I won't post those unless necessary).

Cookie info pulled from top of page

if(isset($_COOKIE['LastRequestDate']))
    $LastRequestDate = $_COOKIE['LastRequestDate'];
else
    $LastRequestDate = "";

Cookie variable displayed

echo "<p>You last requested an internship opportunity on ".$LastRequestDate."</p>";

Here's the code that set's the cookie from another page. I have tried removing the urlencode() but nothing changes.

setcookie("LastRequestDate", urlencode($DisplayDate), time()+60*60*24*7, "/");

Answer 1

use:

<?php
  $DisplayDate = date("l jS \of F Y h:i:s A") ;
  $base64 = base64_encode($DisplayDate);

  setcookie("LastRequestDate", $base64, time()+60*60*24*7, "/");

  $LastRequestDate = $_COOKIE['LastRequestDate'];
  echo base64_decode($LastRequestDate);
?>
