PHP Protect Page Examples

This is an example project that shows how to use PHP to protect a page from being accessed using a number of different techniques.

The one requirement in these techniques is preventing access to a page without using any authentication systems.

Note: We do make use of Basic Authentication here, but only because it is so simple to implement.

Running The Project

This project is set up as a self-contained system that uses DDEV to run. In order to run this project you need to install that system first. Once you have DDEV installed then following the following steps.

• Open up a command line and navigate to the directory that you added the project to.
• Run ddev start to start the project. If you are starting for the first time then this will download everything you need before starting the project.
• Once everything is installed you can visit https://php-protect.ddev.site/ or run ddev launch, which will open a browser and take you to that URL.

When you are finished using the project, run ddev delete to remove everything.

Usage

The project is split into a number of different techniques for protecting a page. These are as follows:

• Basic Auth
• Cookie
• CSRF
• Dynamic Link
• Form
• IP
• JWT
• Referrer
