Is there a way to read data off a remote page?

I know you can use fopen (I think my host may have disabled it,) but anyway, specifically, can you read the source code of it (as you would with view source) using php or even javascript of a remote page, and get specific bits parsing it with PHP?

Okay wait, I have this

<?php
$url = "http://www.google.com";
       $ch = curl_init();
       $timeout = 5; // set to zero for no timeout
       curl_setopt ($ch, CURLOPT_URL, $url);
       curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
       $file_contents = curl_exec($ch);
       curl_close($ch);
?>

 

This uses cURL and is good, works fine. But lets say for example, there was a value in the source generated by the server, but always came before a set constant. If I wanted to just get the URL for the google logo for example, how would I do that using the PHP string functions?
