Creating a multi-page registration form in PHP can be cumbersome, especially with slow load times due to new HTTP requests for each page.
A Single Page Application (SPA) approach enhances user experience by loading HTML once and using JavaScript for smooth navigation.
Benefits of SPA include faster navigation, improved user experience, and reduced server load through fewer requests.
Converting a PHP registration form to an SPA involves setting up the project, creating form pages with JavaScript, and handling form submission efficiently.
