Regex for Yahoo Finance Stock Price

[generalt]

I am trying to grab stock quotes from Yahoo Finance. I am completely new to regular expressions...

The stock price comes like this: <span id="yfs_l84_$symbol">price</span>, where $symbol is the ticker symbol and price is something like 6.75 (no $ sign)

This is what I have so far:

$content = file_get_contents('http://finance.yahoo.com/q?s=$symbol');

preg_match('#<span id="yfs_184_$symbol">#', $content, $match);
$price = $match[1];

echo "Price: $price";
[/CODE]

I really have no idea what I'm doing with preg_match, and the PHP documentation didn't really help much. When I run this code, I get "error: Undefined Offset: 1," referring to $match[1].

What am I doing wrong?

Have you tried the CSV feed via YQL interface, it's pretty handy.
