Get url from another page

Question

I'm very new to PHP so maybe its a very simple question.

One page1.php I want to show the url of page2.php

I tried it like this:

One page1.php:

<?php
$url1="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
?>

On page2.php:

<?php 
echo $url1; ?>

Its a wordpress installation so I need url with permalinks.

maybe its a noob question but I only need to know how this works. Thanks!

Answer 1

You should put them running one time, then page2.php can receive the url.

For example: in page2.php, include page1.php before echo.

So in page2.php:

<?php 
include 'page1.php';
echo $url1; ?>

Answer 2

There are a few alternative solutions for that. I'd advice using file_get_contents function.

Example usage:

$url1 = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$page1 = file_get_contents($url1);
echo $page1;
