PHP scraping to extract the price of items - php

Question

I have tried to create a PHP code to extract the price of items from an eCommerce website. I created a variable where I need to type in the URL of the item and the code will fetch the price of the item and then will display it.
Unfortunately I have tried it for more than 20 times but still I am not getting the result. I went to my professor and he said, he is really busy and will try to find the solution after 3 days. I don't want to wait for 3 days.
Can anyone please help me?

You must try something before coming to Stack Overflow. I hope you won't do this mistake again ;)
Well.. enough of my advice. Here i wrote this code using cURL on PHP. Gets you the amount 40490.
<?php
$ch = curl_init('http://www.flipkart.com/lg-g2-16-gb/p/itmdzuhncfhj9zwt?pid=MOBDZUHGWZ3HMCMF&ref=c35ae3ed-99d5-49d8-ae45-b0d4de3afe41');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$strx=strip_tags(curl_exec($ch));
$str_key="Rs. ";
$end_key=" Inclusive";
$strt=strpos($strx,$str_key);
$end=strpos($strx,$end_key);
echo intval(substr($strx,$strt+strlen($str_key),9));//outputs 40490 (price of the prod)

public function scrapeProductPrice($remote_page_content,$log){
libxml_use_internal_errors(true);
$dom = new DOMDocument();
$dom->loadHTML($remote_page_content);
$xpath = new DOMXPath($dom);
$my_xpath_query = "//table//tr";
$result_rows = $xpath->query($my_xpath_query);
foreach($result_rows as $key => $value) {
$lookUp = strstr($value->nodeValue, PRODUCT_NAME) ? str_split($value->nodeValue, strlen(PRODUCT_NAME)) : 0;
if($lookUp){
return $lookUp[1];
}
}
}
Note:Change $remote_page_content with the page url
