What is the PHP code to open a web page?

How can I get my PHP script to open a web page from a URL? In the browser obviously
Basically I want to pass an html file into a URL which goes to an engine and converts this html to a pdf. It's a bit of a backwards way for doing it but in essence I just need a new window/tab to open with a specified URL.
@StupidShep the $html is already processed into an .htm file; I just need a new window or something to open this file.

$html = file_get_contents('/path/to/html.file');

Then you can do what you want with the $html varible.

Is that what you wanted? If your server is set up correctly you can do the same with URLs:

$html = file_get_contents('http://www.google.com');

<?php

$homepage = file_get_contents('http://www.example.com/');
echo $homepage;

?>

You can also open up a new tab/window with javascript

<script type="text/javascript">

var url = 'http://www.example.com';
window.location = url;

</script>

PHP is server-side. No PHP code is run by the user's browser. Could you explain in more detail what you want to accomplish?
