Redis-Like server, RB-Tree practice

Environment

Web Server : Apache 2.4.23   
Language   : PHP 5.6.24  
Datebase   : Manual implementation (RB-Tree, depend on session)  
OS         : Ubuntu 14.04  

*The server must open cookies and session

APIs

• Get

1.Get the value according to the specified key .

http://localhost/get.php?key=[k_name]
k_name : The name of the key you want to query

2.Get all keys and values

http://localhost/get.php

• Set

1.Insert / update a key-value pair

http://localhost/set.php?[k_name]=[v_val]
k_name : The name of the key you want to insert / update
v_val : The value of the corresponding key

2.Insert / update several key-value pairs

http://localhost/set.php?[k_name0]=[v_val0]&[k_name1]=[v_val1]&[k_name2]=[v_val2]...
The meaning of the k_name and v_val as above.

*All requests are used HTTP-GET.

Notice

For data persistence, my idea is to serialize the entire rb-tree to a local file each time the rb-tree updated and reload the file in an unexpected crash or reboot, and deserialize the tree to memory.
Because of the time constraints, the RB-tree only to implement the insert and query, and didn't implement data persistence, the RB-tree temporarily in the session.

Ehhhh, ok i admit that my ability to implement is insufficient.
