Here's an example of something that works and doesn't work
==============================================
function GetWebPage( $url, $maxsize=1000000 )
{
	//	Open a connection to the site
	$fp  = fopen ($url, "r");

	//	Did we find it?
	if (!$fp) 
	{ 
		//	Nope, return nothing
		return "";
	} 

	//	Get the page
	$webpage = fread($fp, $maxsize); 

	//	Close the connection
	fclose( $fp );

	return $webpage;
}

//	Doesn't work get error
print GetWebPage("http://ir.stockmaster.com/c/pbn/stocks.html");

//	 It Works
print GetWebPage("http://www.phpbuilder.com/columns/");

=========================================

// first GetWebPage fails
//
Warning: fopen("http://ir.stockmaster.com/c/pbn/stocks.html","r") - No error in D:\extranet\WebTop\site\t.php on line 25

Turns out that the problem is redirects. fopen() doesn't follow
redirects any more. The semantics for fopen() and redirects is
being discussed.
