In today's digital age, online voting systems have become increasingly popular as they provide a convenient, secure, and transparent way to conduct elections. In this article, we will discuss an online voting system project in PHP and MySQL, including its features, source code, and GitHub repository. We will also provide a portable version of the project that can be easily deployed on any server.
To prevent double voting while maintaining anonymity, a separate audit ledger tracks who voted in which election, without linking them to how they voted. SQL Injection Protection In today's digital age, online
