Comment:

 fsockopen, fopen: `fread()+fwrite()` loop, easy

 streams: `stream_copy_to_stream($http_handle, $new_file_handle);`

 HTTP Extension: I cant see a case there which allows for streaming
 directly to files, So will probably have to read into memory, and write it
 out.

 cURL: Can use `CURLOPT_FILE` to specify where to write the output,
 `CURLOPT_WRITEHEADER` or `CURLOPT_HEADERFUNCTION` should be able to be
 used to capture the header data


 Some of the classes might be able to be unset or destroyed better to
 decrease memory usage after a request is made.
