##post##post is a request method, In addition, there is also a get request method. In PHP, the predefined $_POST variable is used to collect values ​​from the form with method="post".

The information sent from the form with the POST method is invisible to anyone (will not be displayed in the browser's address bar), and there is no limit on the amount of information sent.

Note: By default, the maximum amount of information sent by the POST method is 8 MB (can be changed by setting post_max_size in the php.ini file).
