Wow, I had no idea that existed; what an incredibly ugly implementation. Even the name is weird (why "header" singular when it contains an array of headers?) The only other local-scope variable listed next to it in the manual [1] is $php_errormsg, which has to be enabled with an ini setting. If the information is useful at all, then I guess a get_last_http_response_headers() function would be less magic - although that would presumably mean the data had to be stashed indefinitely in an internal global just in case it was asked for, rather than it naturally falling out of scope. We could just say that if you're using a shortcut like file_get_contents, you can't have it both ways and access metadata afterwards. It's just a pity ext/curl is so faithful to the underlying lib, and therefore so awkward to use for simple cases.
