I need to crawl through a page and get the contents of a particular div. I have php and javascript as my two main options. How can it be done?

This is quite a basic method to do it PHP and it returns the content in plain text. However you might consider revising the regex for your particular need.

<?php
  $link = file_get_contents("http://www.domain.com");
  $file = strip_tags($link, "<div>");
  preg_match_all("/<div/>(?:[^<]*)</div>/is", $file, $content);
  print_r($content); 
?>

There are many ways to get the contents of an url:

First Method:

http://simplehtmldom.sourceforge.net/

 Simple HTML DOM Parser

Second Method :

<?php

  $contents = file_get_contents("http://www.url.com");
  $contents = strip_tags($contents, "<div>");
  preg_match_all("/<div/>(?:[^<]*)</div>/is", $contents, $file_contents);

?>

Third Method:

`You can use jquery like Selectors :`

您可以使用SimpleDomParser，如http://simplehtmldom.sourceforge.net/manual.htm中所述，但它需要PHP5 +，不过好处是，您可以通过选择器（如jQuery）在HTML页面上找到标签。
