PHP: Data from cURL, HTML Scan

How can i scan a html page, for text within a certain d开发者_高级运维iv?

The simplest way to do this would be to use Simple HTML DOM parser

// Create a DOM object from a URL
$html = file_get_html('http://www.google.com/');    

// Find all <div> which attribute id=foo
$ret = $html->find('div[id=foo]');

You can also do this using the DOMDocument class.

Usage is pretty straight-forward:

$dom = new DOMDocument();
$dom->loadHTML(file_get_contents($url));

// Example:
$dom->getElementById('foo');

Documentation is here.

An example of real world usage can be found here.

You could use build in functionality as suggested by others or you could try the Simple HTML DOM Parser is implemented as a simple PHP class and a few helper functions. It supports CSS selector style screen scraping (such as in jQuery), can handle invalid HTML, and even provides a familiar interface to manipulate a DOM.
