waSaf Posted November 25, 2009 Author Share Posted November 25, 2009 rephrase my problem.... i intend to get few data on this specific page, eg. www.data123.com/page.php the method that i am using is, to parse the whole page into source code and use regex to filter what i want... the page have a form ($_POST) so that the visitor can select the data base on the date submitted. so, how to get the source code each time i submit new date? because im using file_get_contents here and the parameter used is only URL, while each time i submit new date, there is $_POST variable there...

cags Posted November 25, 2009 Share Posted November 25, 2009 Using cURL instead of file_get_contents you can send $_POST variables and capture the result. You can then scrape the result. Depending on what information your scraping you might be better off using some sort of DOMDocument rather than Regex, but thats another matter.
