Extracting live data from website using PHP

Question

I have viewed the question on Extract data from website via PHP regarding this issue. But I couldn't solve my problem. I am trying to extract a live data from a website. It's silver price. It changes everyday and I need to extract the latest data.

I am trying to extract from http://www.maybank2u.com.my/mbbfrx/silver_rate.htm

I have done file_get_contents("http://www.maybank2u.com.my/mbbfrx/silver_rate.htm");

But when I tried to preg_match() the price. I couldn't find the correct way of doing it. Appreciate if someone here could help me.

Sorry for bringing up the same question which are already in the threads, but I just couldn't solve it.

I have tried preg_match('/SELLING(RM/\g)\td>\tr>/'); But I'm not entirely sure about that as well because the price should be changing everyday so I'm guessing it should be something to do with tags. — mfmz, Jan 23 '13 at 10:49

As others suggested you using HTML/DOM parsers (and that's right), let me also suggest http://gskinner.com/RegExr/ to test out your regexes. — Evgeniy Chekan, Jan 23 '13 at 11:36

Please dont use regex to parse an html document.
Use html/dom parser instead.
Take a look at this link.
It should give you a start how to extract the data.

Don't use regular expressions (preg_match). Use a dom parser. I'd recomomend the one at http://simplehtmldom.sourceforge.net/.

Once you have a script that would scrape the page you're interested in, instruct your server to execute it every day by setting up a cron job.
