On the mobile side, click the Upload button to eject the camera:

Mobile app upload Image instance: API interface:

Questions: App upload Avatar, PHP as the API side should be how to receive image information?

Uploading part of the code is not a problem, mainly the server side how to receive the app-side picture information. In the B/s architecture, you can set the Enctype= "Multipart/form-data" directly through the form form, and the image information is in the $_files array. So is it true in the C/s mode?

answer 1 (see mode one): generally using binary stream transmission, the client is binary, the server receives, and then file_put_contents write to the file. File name format, where files are placed, these own definitions. 

Answer 2 (see mode II): The Android or iOS client simulates an HTTP POST request to the server side, after the server receives the corresponding POST request (obtains the picture resource through $_files), returns the response information to the client. (This is the same way you get HTML-submitted methods)

mode one: the picture is Base64 encrypted into a string, transmitted

Description: iOS or Android: by base64 the image to get the string, passed to the interface

 interface: Base64 decode the received string and upload it to the specified location via the File_put_contents function
