Strictly speaking, `main` isn't even a special function in C. It's only special to your C library and linker and something something I forget the details. Anyway it doesn't matter at all; you could leave off the `if` in Flask's example and never notice any difference. Just emerged as common practice to bracket off stuff like that /in case/ you ever decide to import your script as a module. Part of my problem with PHP is that it doesn't seem to know what it is; there are the C parts, and the C++/Java parts, and both sides are sort of glued together with Perl influence, yet don't very well interoperate otherwise. I have a pretty patchwork background and I could get work done in just about any language you'd pay me to use. I'd even happily write a web app in C. Doesn't make PHP any more attractive.
