How to deploy a PHP basic application scratch with Docker

1. Create a directory (ex. php-demo)
2. Create Dockerfile in root $touch Dockerfile

    FROM php:latest ## Pull the image from dockerhub
    COPY index.php /var/www/html/index.php ## Copy file index.php to directory /var/www/html in image.
    EXPOSE 80 ## Port 80 is exposed for apache.
    CMD ["usr/sbin/apache2ctl", "-D", "FOREGROUND"] ## Apache started the container.

These lines of code represent the image we're going to use along with copying the contents of the current directory into the container.
