fwrite () Assistance

[Anon]

Hi All:

I've reviewed the manual, and various books multiple times, but unfortunately I'm still getting an error "supplied argument is not a valid file-handling resource". So I'm hoping someone can look at my code in point me in the right direction.

The goal is to take a syndicate feed (that is only provided via http://), and write it to file for ongoing use. I'll worry about setting seek times, after I can actually get the feed written to file. My code is...

<?

$cache = "/alnisa/macTracker.txt";
$backend = "http://www.versiontracker.com/cgi-bin/syndicate.pl?USER=temp&PLATFORM=mac&TYPE=hot&FORM=htmlfrag";
$fpread = fopen($backend, "r");

if ($fpread =="") {
	echo("Did Not Open TechTracker Data Feed");
}

else {
	$file = (fgets($fpread, 5000));

		if($file = $fpread); {
			fwrite($cache, $file);
		}

}

@fclose($backend);

?>

The error is always at the fwrite line. But the format seems correct. My only guess is that the issue lies with writing to a different file than was read from, but I can't figure out how to get around that or how to test if that's the actually cause of the error.

Any help would be greatly appreciated.

Simple overlook, I am sure.

You forgot to open the output stream for the $cache filename.

<?

$cache = "/alnisa/macTracker.txt";
$backend = "http://www.versiontracker.com/cgi-bin/syndicate.pl?USER=temp&PLATFORM=mac&TYPE=hot&FORM=htmlfrag";
$fpread = fopen($backend, "r");
$cacheFP = fopen($cache, 'w');

.. rest of your code...

fwrite($cacheFP, $file);

Hope this helps.

Thanks much. I addedd the open output stream, and then made some other minor adjustments, but it now pulls and writes perfectly fine.
