Simple implementation of address book collection in php, my first php, suitable for novices

It originated from the need to organize the address book. I originally used file investigation. Now that I have learned PHP, I will try it myself.
The program is short and concise, suitable for learning.
There are two files, bj.html is used for display and collection Form information.bj.php is used to process data and feedback results.
The highlight is that you can upload reading avatars.
In fact, there is also a test.php for debugging and intermediate processing. Let’s start with this one.
The comments are very detailed , tags, functions, right-click to search.
Because there are many web directories, put them under the ./1/ folder, and set a bookmark in Firefox for easy access
When deploying, change bj.html to index.php

Originally thought To build an IPv6 free Internet application platform (now I know it is an oauth open platform), I started to learn PHP. PHP is the simplest, but it took me a year to learn the first program, so be careful!
