RE: [PHP] Retrieving data from a URL in PHP
Yahoo keeps moving things around. I had the same result with a news feed.
If you research the page at
http://finance.yahoo.com/?u
you should be able to figure out how they get quotes.
good luck,

Subject: [PHP] Retrieving data from a URL in PHP
The code that follows is from Welling and Thomson's book on PHP and mysql
(page 372)
I've tried it on Apache/ MS Windows 98 / PHP and I get the following line:
No quote available.
Questions...
1. Why can't I retrieve the present stock quote?
2. What is the variable
$quote
represent in the script?
I cannot find where $quote has been assigned.
Thanking all in advance.

Try
$content = implode('', file(URL...) );
rather than the fopen(), file pointer route.

You may need a user:pass appended to the URI.

One ought never to turn one's back on a threatened danger and
try to run away from it. If you do that, you will double the danger.
But if you meet it promptly and without flinching, you will
reduce the danger by half.

RE: [PHP] Retrieving data from a URL in PHP
To illustrate what's wrong with the code from the book,
the following code works... notice what's different.
But really, you should've just loaded the URL and noticed
there's no $[0-9].[0-9] and instead it was bold.
problem solved.
$symbol=ibm;
echo h1Stock Quote for $symbol/h1\n;
$theurl=http://finance.yahoo.com/q?s={$symbol}d=v1;;
if (!($fp=fopen($theurl, r)))
{
echo Could not open the URL;
exit;
}
$contents= fread($fp, 100);
fclose($fp);
if (preg_match(/(b[0-9]+\.[0-9]+\/b)/,$contents, $quote))
{
echo $symbol was sold at: ;
echo $quote[1];
}
else
{
echo No quote available.;
}
echo br.This information retrieved frombr.a
href=\$theurl\$theurl/abr.on .(date(l jS F Y g:i a T));

I cannot find what the variable -or array - $quote has been
assigned to.
Please see:
echo $quote[1];
