[PHP-WIN] Retrieving data from a URL in PHP From: Anthony Ritter (tony <email protected>)
Date: 06/05/02

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."

My questions...

1. Why can't I retrieve the present stock quote?

and

2. What does the variable

$quote

represent in the script?

I cannot find what the variable -or array - $quote has been assigned to.
Please see:

echo $quote[1];

below

Thanking all in advance.
