twister

Twister is a fast and light-weight micro-framework.

Actually, a more precise definition of this code release would be; Twister is a set of fast and light-weight components around which a framework can be written

At the heart of the framework, sits a very flexible, simple and elegant Inversion-of-Control (IoC) Container. In fact, there are NO global variables, NO define's, NO pipeline, NO Kernel and NO App; just the Container. The Container controls the entire flow of code (except routing), with a custom execute() function (written by you); which is actually just an anonymous callback function inside the Container, called from the Front Controller (index.php); even the name of that function can be changed in the config file. ie. There is NO pre-programmed flow of the program or hard-coded Kernel/App. Most things are handled/registered with the IoC Container, objects are pre-configured and lazy-loaded on request/use only!

Along with the Container, comes a very flexible and fast router (inside the Request class). I consider this router to be THE fastest router I've tested, with the same functionality. It includes the ability to filter by method (GET/POST), and optional parameters like /user/{id}[/{name}] Another somewhat unique capability is the ability to pre-define the patterns associated with named parameters eg. id->\d+ So everytime you specify {id}, {date} etc. in any route, the same patterns are re-used,         or you can specify custom patterns with {id:[0-9]+} or {id:uuid} where uuid=>[A-F0-9-]+ etc.    Two design choices make the router fast: 1) Everything is configured/loaded from a config array (which is usually cached by APC/Xcode/PHP7) 2) The router splits the request uri by '/', doing an isset array lookup for the first path segment 3) The router only takes further action after the first segment (eg. /admin/, /login etc.) is resolved

Although Twister is a fully functional and useable framework (based on my personal framework), it's more a proof-of-concept for me to demonstrate my capabilities and design decisions.

Benchmarks:

All tests were done with a skeleton hello world application on the same PC. Laravel and Symfony were NOT configured to establish a database connection, while Twister WAS! With a database connection, Symfony dropped to 9-12 requests per second, and Laravel 12-16 rps, Twister was running about 50x-100x faster than Symfony and Laravel
