PHP Simple DOM Parser Parse Current PHP Page - php

Question

I am using the PHP Simple DOM parser to extract all of the image sources on a given page like so:
// Include the library
include('simple_html_dom.php');
// Retrieve the DOM from a given URL
$html = file_get_html('http://google.com/');
// Retrieve all images and print their SRCs
foreach($html->find('img') as $e)
echo $e->src . '<br>';
Instead of using Google.com, I wish to use a page on Wordpress's admin (backend) area. These pages are PHP pages, not HTML (but the page has standard HTML throughout). How would I use the current page as the $html variable? PHP newbie over here.

Using this library dxtool found here.
Login
require 'WebGet.php';
$w = new WebGet();
// using cache to prevent repetitive download
$w->useCache = true;
$w->cacheLocation = '/tmp';
$w->cacheMaxAge = 3600;
$w->cookieFile = '/tmp/cookie.txt';
// $login_get_data and $login_post_data is associative array
$login = $w->requestContent($login_url, $login_get_data, $login_post_data);
Visiting Image containing page
// $image_page_url is the url of the page where your images exist.
$image_page = $w->requestContent($image_page_url);
Parse images and display
$dom = new DOMDocument();
$dom->loadHTML($image_page);
$imgs = $dom->getElementsByTagName("img");
foreach($imgs as $img){
echo $img->getAttribute("src");
}
