Depending on the content of the DIV you would want to call either the innerHTML or innerText for the div.

from a different domain name? I guess you will get a Permission Denied error if you try to retrieve other site's content using javascript XMLHTTP request, but certainly I'm not sure other methods available in php whether can accomplish this or not.

Scrape is the technical terminology here
Scrape DIV in this case

Disclaimer: Don't scrape if you don't have permission
</php
 
$url = "http://www.theremotesitehere.com/page.html";
 
$raw = file_get_contents($url);
 
$newlines = array("\t","\n","\r","\x20\x20","\0","\x0B");
 
$content = str_replace($newlines, "", html_entity_decode($raw));
 
$start = strpos($content,'<div class="unique name here"');
 
$end = strpos($content,'</div>',$start) + 6; // add 6 becuase of </div> is 6 chars long
 
$div = substr($content,$start,$end-$start);
 
// you can go further and extract inside your div as you wish now
// by accessing $div
 
?>
