Php5 common compatible public files.-PHP source code

Php 5 is a common compatible public file. every new project requires many php modifications for environment configuration. For this reason, I have compiled this generic php header file.
Save the code as a php file and introduce it to the project.

The code functions as follows:
1: The normalization encoding problem, UTF-8, time zone, and number length are all changed.
2: For canonicalized character escaping, all use the standards after php5.3 and do not convert them.
3: the session and gzip are used to determine the startup. This helps prevent implicit conflicts.
4: sort SERVER arrays to hide some unsafe segments and add data starting with HTTP _, such as memory usage, start time, current url address, ip address, get, post and so on. as long as you print out the $ _ SERVER array, basically a lot of data will be available, and it is super Global.
