PHP implements the method of saving browsing history page URLs to cookies, Phpcookie

This article explains how PHP implements a way to save a browsing history page URL to a cookie. Share to everyone for your reference. Specific as follows:

Save the Browsing history page URL to a cookie, with a general idea like the following code, which is somewhat different from the actual application.
Copy the Code code as follows: <?php
/*******
Note: The cookie can only save the string in this instance, need to save multiple URLs (historical access Records), the idea is to first convert the URL array into a string, and then save, read, and then loop read
*******/

First assume that the current URL is: http://localhost/php/?id=1
$id = $_get[' id '];

if (Isset ($_cookie[' his ')) {
$urls = $_cookie[' His '];//read COOKIE
$arr = Unserialize ($urls);//String back to the original array
$arr [] = $_server[' Request_uri '];//the current page URL is added to the array
$arr = Array_unique ($arr);//Remove Duplicate
if (count ($arr) >10) {//Save only 10 Access records
Array_shift ($arr);
}
$urls = serialize ($arr);//stored as a string,
Setcookie (' his ', $urls);//Save to Cookie
}else{
$url = $_sever[' Request_uri '];//gets the current page URL
$arr [] = $url;//Save the current URL to an array
$urls = serialize ($arr);//stored As String
Setcookie (' his ', $urls);//Save to Cookie
}

echo "Previous page

";//previous page, Access test
echo "Next page";//Next page, Access test

?>

History visit page

<?php foreach ($arr as $v) {?>

• "><?php Echo $v;?>

<?php}?>

I hope this article is helpful to everyone's PHP programming.
