grab gold value using curl

Question

I am new to php curl, can you help me to write code for grabbing gold value from this page http://www.domain.com/gold.php

from following line i just want 27742.00

Gold price today in India (Rs/10gm) is 27742.00 (-67)

Does it require HTML parser or just curl can do it alone?

Thanks for your help.

Regex can do this for you.

preg_match('#Gold price today in India <b>\(Rs\/10gm\)</b> is <b>([0-9\.]+)#', file_get_contents('http://www.marketonmobile.com/gold_price_india.php'), $matches);
echo 'The price is: '.$matches[1];

This regex needs some work to ignore or parse the `` tags in the text. – Sjoerd Dec 22 '11 at 13:19
@Sjoerd Yeah, posted it before testing. The poster didn't include the in his question. – Tom van der Woerdt Dec 22 '11 at 13:20
good suggestion, yes we could use regex for this but somehow above code is not returning results. – seoppc Dec 22 '11 at 13:22

You can retrieve the page with curl or file_get_contents(). When you have the page, you can get the value with a HTML parser or a regex.

cUrl alone can not parse HTML, so you need a HTML/Text parser that works on the return value of the cUrl request.

Example HTML parser with xpath:

$url = 'http://www.domain.com/gold.php';
$expr = 'string(//div[@class="gold"]/b[2]/text())';

$doc = new DOMDocument();
@$doc->loadHTMLFile($url);
$xp = new DOMXPath($doc);
$price = trim($xp->evaluate($expr));
