How to crawl and display the details of a url? - php

Question

i am currently having problem displaying the image and price of a url from flipkart, what i want is to display the product image and price of a url and continuously crawl all the url's following it and display the details for the same in one page, but i get the error saying redirection limit reached, failed to open stream.
here is my code:
<?php
ini_set('max_execution_time', 4000);
$to_crawl = "http://www.flipkart.com/apple-iphone-6/p/itme5rf6ewg7trwz?pid=MOBEYGPZAHZQMCKZ&otracker=from-search&srno=t_4&query=apple&al=hplRX0gsd%2BUs3897GU7MA33GdyuXyA9x5heu%2FXnCd8gCFiEqsIXwVoaLq2lx4bRfFLwHQxVDMNU%3D&ref=cfd05202-e814-4bb4-bbe2-422b4ecc6df9";
