Get specific html content from other site with PHP

问题

What you are asking for is called as web scrapping ,I have done this a few months back, the process goes like this,

Make a HttpRequest to the site from which you need the content,check the php class for it
Use a DOM parse library for handling the downloaded page (it would be in html),simple HTLM DOM would be a good choice
Extract your required information

Here are some tutorials for you,

follow steps to achieve this

STEP1:-

First get the contents using file_get_contents in a php file

ex: getcontent.php

<?php

echo file_get_contents("http://www.icheckmovies.com/movies/checked/?user=robinwatchesmovies ");

?>

STEP2:-

CALL the above script using ajax call and add the content to a visibility hidden field in the html.

ex:

$('#hidden_div').html(response);

html:-

<html>
<body>
<div id='hidden_div' style='visibility:hidden'>
</div>
</body>
</html>
