To effectively use PHP, first ensure you have a web server set up on your computer, either through Windows IIS or Unix Apache. Resources like the official PHP website (php.net) provide essential documentation. For easier installation, consider using packages like FoxServ, which streamline the setup of Apache, MySQL, and PHP on both Linux and Windows. If the goal is to create a simple application, such as a text submission box for a message board, focus on learning both installation and programming aspects of PHP. Starting with a local server environment will facilitate development and testing.
