在PHP页面之间传递URL

Question

I was wondering how I can pass a URL to another web page using PHP. I know if I were to use an HTML form I could have a hidden field with the value being the URL I want to get.

How can I pass the URL along to another page without using a form?

Answer 1

If the page is your own, you could use a session variable.

Answer 2

您可以使用$_SESSION或cookie 。

Answer 3

PHP has a server global variable which includes a referrer variable.

$_SERVER['HTTP_REFERER']

http://php.net/manual/en/reserved.variables.server.php

You can echo this and it will output the page which the user came from.

Answer 4

You could pass it using a get query,which is in a way form data, so i won't go into it OR a session variable. On the sender page

session_start();
$_SESSION['url']="http://site.com"

and on the receiver

session_start();
$url=$_SESSION['url'];
unset($_SESSION['url'])l

Answer 5

You can initiate sessions.

Put session_start(); at the top of every page (normally by including a header or function). The session_start(); needs to come before any HTML output.

Then on your referring page, you can save values into the session array: $_SESSION['URL'] = "myurl.com";

On your second page, you can reference it just like any other variable: echo $_SESSION['URL'];

Answer 6

<a href="somepage.php?url=<?php echo urlencode("http://example.com/page"); ?>">Link</a>

然后， somepage.php将在变量$_GET['url']接收URL。
