    • Takeaway: Avoid MVC, consider having all of the logic for a page contained on that page, with the exception of some functions.

      • What finally pushed me to abandon the framework approach was realizing that I was flipping through too many files to follow the flow of control, and that too much of my code was there only to comply with the framework’s separation of concerns. Having business logic scattered around in multiple files and classes is painful because I work on a 13″ laptop with vim. Maybe MVC frameworks are easier to work with on multiple 23″ screens, but on a small screen the buffer changes and screen splits cause too many mental context switches. I wanted to see everything that was happening on a single page, so I could keep it in my head and think through it.

        Now I have under 4,000 lines of PHP written in a more readable and, I think, maintainable style. URLs map to individual files (with some simple Apache rewriting to support pretty URLs like /email/inbox mapping to email_inbox.php). Every PHP file that corresponds to an HTTP request is written in the classic PHP “mullet” style: business in the front, party in the back. Request handling and business logic, including querying/updating the database through the models, is at the top of the file, followed by HTML that can only use variables defined in the same file and a handful of global utility functions. There’s no embedded SQL or database operations—that’s still in the models, and once the boundary is crossed from PHP to HTML there’s no reference to model functions or any embedded blocks of PHP code. It’s now easy to find where every request is handled and to follow it through to the response (HTML output) in a single file. Common PHP functions and HTML code (page headers and footer, style sheets, Javascript) are in separate files. There’s no more boilerplate, and no more long blocks of code that simply copy validated user inputs or a database query result into a structure to pass to a template renderer.
