$symbol="ibm"; echo "<h1>Stock 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, 1000000); fclose($fp); if (preg_match("/(<b>[0-9]+\.[0-9]+<\/b>)/",$contents, $quote)) { echo "$symbol was sold at: "; echo $quote[1]; } else { echo "No quote available."; } echo "<br>"."This information retrieved from<br>"."<a href=\"$theurl\">$theurl</a><br>"."on ".(date("l jS F Y g:i a T")); --- Scott Hurring Systems Programmer EAC Corporation [EMAIL PROTECTED] Voice: 201-462-2149 Fax: 201-288-1515 > -----Original Message----- > From: Anthony Ritter [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, June 05, 2002 4:53 PM > To: [EMAIL PROTECTED] > Subject: [PHP-WIN] 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." > > My questions... > > 1.
