PHP Form submitting

If we have the following structure in our application:

📁 application_folder_name
- 📄 index.php
- 📄 handle_form.php
- 📄 main.js

And we fill our index.php with the following content just to get a basic website with a form working. You should be able to run this through a php-server of your choice.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Check if User Exists

	#!/bin/sh

	cat <<EOF >/tmp/adminer.conf
	server {

	listen 80;
