The feedback directory contains a feedback form application that demonstrates the use of PHP with MySQL. The application contains:

• A home page (index.php) with a feedback form.
• An about page (about.php) with information about the application.
• A feedback page (feedback.php) that displays feedback submitted by users.
• The config directory with the database configuration and SQL file to set up the required tables.

Pre-requisites

• PHP installed on your machine
• A web server like Apache or Nginx (or all-in-one tools like XAMPP or Laragon)
• A MySQL database (for the feedback form application)
• A code editor like Visual Studio Code or Sublime Text

Getting Started

To run the scripts in this repository:

1. Clone the Repository

   git clone https://github.com/stekatag/php-crash-course.git
   cd php-crash-course
   

2. Run a Local Server Use a tool like XAMPP, Laragon, or PHP's built-in server to run the PHP scripts. For example, you can use PHP's built-in server by running the following command:

   php -S localhost:8000
   

3. Access the Scripts Open your browser and go to http://localhost:8000 followed by the script name, e.g., http://localhost:8000/01_output.php.

4. To run the feedback form application:

   • Create a MySQL database and import the feedback/config/php_dev.sql file to set up the required tables.
   • Update the database configuration in feedback/config/database.php with your database credentials.
   • Access the feedback form by going to http://localhost:8000/feedback/index.php.

Course Overview

This course provides practical examples and explanations for various PHP concepts. Each script is a standalone example, so you can run them independently to see the output and understand how each concept works.
