php api digest authentication multipart form data

what is the best way for a php rest api server to receive images from a client (here iphone).

Currently, we are sending the base 64 encoded content of the image fi开发者_运维技巧le to the api server from iphone as a POST variable. At server end, we decode this variable and then we are creating a new file based on the decoded content. this works fine.

What are the other ways we can receive images?

For ease of receiving it in PHP, post it as a binary with multipart/form-data and access it via the $_FILES array. You could also do it as an HTTP PUT.
