I'd like to mess around with PHP and del.icio.us, but I can't seem to figure out how to do HTTP authenticaiton with PHP. I need to send
a) the request for the page and
b) the http authentication info. I've found out how to do the authentication header, but not the request itself.
header("Authorization: Basic
base64string");
where
base64string is my del.icio.us username and password base64 encoded in the format username

assword. My question is...how do I go about sending the request for the page right before that?
