Capture referring url then create link based on it

[sqc]

Hello, newbie here.

 

Let’s say this url refers to my page:  www.referringpage.com/folder/abc123

 

(1) I want to capture the "abc123" part that comes after the last forward slash and assign it to a variable named "id"

 

(2) Then I want to create a clickable link:  www.mynewlink.com/folder/abc123

 

Probably pretty simple to the vets.  Thanks in advance!

http://php.net/parse_url

 

And then

As I mentioned, I know very little php.  This is what I tried that didnt work:

$url = $_SERVER['HTTP_REFERER'];

$id = var_dump(parse_url($url, PHP_URL_PATH));
echo $id;

“Didn't work” is a bit vague.

<?php

$_SERVER['HTTP_REFERER'] = 'https://www.mynewlink.com/folder/abc123';

$url_path = parse_url($_SERVER['HTTP_REFERER'], PHP_URL_PATH);
$url_id = basename($url_path);

var_dump($url_id);

First of all, var_dump() doesn't return anything. So your $id will be null.

 

Secondly, parse_url() returns an array not a string. Did you look at the manual?

 

EDIT: Oops sorry, you're using a component flag, so it does return a string.

Thanks.  this returned:   string(6) "abc123"

 

If the actual refering page url was  www.referringpage.com/folder/abc123 how would I take what youve done but actually capture the url and then print the clickable link http://www.mynewlink.com/folder/abc123
