HyperF - Project

It is extremely important that HyperF processes do not overwrite shared variable data. This can occur with overload.

Create - Project

composer create-project hyperf/hyperf-skeleton "project"

Install - Watcher

composer require hyperf/watcher --dev

Install - UUID

composer require ramsey/uuid

Server - Start

cd project ;
php bin/hyperf.php server:watch ;

HyperF - APP

APP - Router

Router::addRoute(['GET', 'POST'], '/overlapping/data', 'App\Controller\ControllerOverlapping@data');
Router::addRoute(['GET', 'POST'], '/overlapping/value-a', 'App\Controller\ControllerOverlapping@value_a');
Router::addRoute(['GET', 'POST'], '/overlapping/value-b', 'App\Controller\ControllerOverlapping@value_b');
Router::addRoute(['GET', 'POST'], '/overlapping/value-c', 'App\Controller\ControllerOverlapping@value_c');
