I'm trying to make a script that makes a HTTP POST with some headers, and with a file as the body. I've found all sorts of documentation online about making a HTTP POST with headers, but can't figure out how to make the POST with a file as a body.
The file is actually uploaded via another HTML POST. My program's architecture looks like this:
User uploads file via HTML Post -> intermediary script -> POST file to a website
Is there some good documentation on how to make a HTTP POST in PHP with both headers and a body? Alternatively, does anyone have some quick sample code? This should be really simple, but I can't seem to figure it out. :(
