CLAMP Campus Adventures

I’ve been at it again. This time I took someone else’s PHP Code for a counter of Firefox downloads and changed it to utilize the curl library rather than fopen (which is banned on Dreamhost for security purposes).

Here’s what the script outputs and here’s the script:

$NumDownloads = GetNumFirefoxDownloads("http://feeds.spreadfirefox.com/downloads/firefox", 80, 25);
