Using Phpinfo to implement the PHP configuration statistics process

Everyone knows that the phpinfo (), which is used to display the server configuration, is a very useful tool for installing a new server, and is a very useful tool to communicate with various managers.

Of course, after use, it is usually removed or simply provided to a small number of people, indeed, phpinfo itself may be very dangerous. Sometimes he even has a flaw in XSS injections.
