fopen for opening a page doesn't work!

[Bijan]

Hi, I'm using this simple code to open a page with fopen:

<?PHP
$webpage = "http://www.irandiba.net";
$fp = fopen( $webpage, "r+") or die("Couldn't open the following URL : $webpage");
while ( !feof( $fp))
{
	print fgets( $fp, 1024);
}
?>

But it gives me this error message:

Warning: fopen("http://irandiba.net","r") - Unknown error in /home/www/sajharsanat/test/fopen.php on line 8
Couldn't open the following URL : http://irandiba.net

It's something wrong about this message I think; if you look at the URL that it gives as the source of error, you see that it doesn't have www in it. My $webpage is equal to "http://www.irandiba.net", but in the warning message I can't see the WWW. What's going on?!

Why nout use:

$webpage = 'http://www.google.com';

HEADER(Location: '$webpage');

Hi
Well, I know about that and also the fsockopen or just simply using <HTTP EQUIV..... > to redirect. Let's say that it's a kind of hypothetical question! I wana know why this fopen doesn't work, but everywhere I read that it should work!

Thanks for your reply anyway,
