Overview

Derives absolute URL from relative and source URLs.

Useful when:

• extracting full HREF URLs for links in a HTML document
• determining absolute new URL for a 301 redirect where the HTTP server returned a relative Location value

Usage

The "Hello World" example

<?php
use webignition\AbsoluteUrlDeriver\AbsoluteUrlDeriver;
use webignition\Uri\Uri;

$base = 'https://example.com';
$relative = '/path?query#fragment';

$this->assertEquals(
    'https://example.com/path?query#fragment', 
    AbsoluteUrlDeriver::derive(new Uri($base), new Uri($relative))
);
