At last, this post was edited by qbnrg968119 at 20:00:48 on. a simple code for signing in is as follows: I want to upload the code to the Baidu BAE space. I can save the following code as a php file and package it, is this single PHP file uploaded? Or do I have to write other code and other files to work?

I tried it and uploaded it to the Baidu BAE space. after I uploaded the zip file, it will report an error:
Parse error: syntax error, unexpected T_STRING in code/builder/work/appidwihbq31d16/0/uxinsign. php on line 7
Errors parsing code/builder/work/appidwihbq31d16/0/uxinsign. php
Is there an error in the code itself?

Cainiao has never done network programming and has only done desktop software. php does not understand it at all. thank you very much !!

It may be that your file contains the BOM header, so
