PHP a file to take care of the micro-JSSDK Configuration Example code

PHP a file to fix JSSDK configuration:
including the cache, including HTTPS communications, get access_token, signatures and anything else. However, the preventive programming is relatively small, commercial use, the need to improve the code.
Use Posture
