REACTPHP INTERNALS: EVENT LOOP TIMERS · @ZHUKSEREGA under the hood, the event loop creates an instance of Timer and adds it to the list of internal timers. To create a timer the loop provides an interval to trigger the callback and the callback that should be executed. The last false argument says that the timer is going to be a INTRODUCING PHP-WATCHER · @ZHUKSEREGA This task can be solved with the watcher: php-watcher public/index.php --watch src --watch config. The command above executes PHP script public/index.php and starts watching directories src and config for changes. Once, any PHP file in these directories is being changed the EVENT-DRIVEN PHP WITH REACTPHP: EVENT LOOP AND TIMERS Event loop is the core of the ReactPHP, it is the most low-level component. Every other component uses it. Event loop runs in a single thread and is responsible for scheduling asynchronous operations. There is no other code being executed in parallel. Event loop is the only synchronous thing. BUILDING A RESTFUL API USING REACTPHP: JWT AUTHENTICATION Authenticate ReactPHP RESTful API with JWT authentication. Previously we have used Basic HTTP Authentication to protect our RESTful API.This authentication method is pretty simple, but in most cases, it can be used only in the internal network with server-to-server communication. HOW TO SPEED UP THE CODE REVIEW · @ZHUKSEREGA code style fixes (removing redundant doc blocks) At the same moment, the feature itself is just 10 lines: As a result, the reviewer has to look through all the code and: check that the refactoring is OK. check that the feature was implemented correctly. detect whether it was an automatic IDE change or a human-made one. USING ROUTER WITH REACTPHP HTTP COMPONENT · @ZHUKSEREGA Using FastRoute with ReactPHP Http Component. Router defines the way your application responds to a client request to a specific endpoint which is defined by URI (or path) and a specific HTTP request method (GET, POST, etc.).With ReactPHP Http component we can create an asynchronous web server.But out of the box the component doesn’t provide any routing, so you should use third-party LARAVEL 5.0: USE DATABASE AND ELOQUENT FOR LOGGING Creating logging system based on Eloquent in Laravel 5.0.
