https://github.com/phalcon/cphalcon/blob/master/phalcon/di.zep

line 215 to 230

    if typeof eventsManager == "object" {
        eventsManager->fire("di:beforeServiceResolve", this, ["name": name, "parameters": parameters]);
    }

    if fetch service, this->_services[name] {
        /**
         * The service is registered in the DI
         */
        let instance = service->resolve(parameters, this);
    } else {
        /**
         * The DI also acts as builder for any class even if it isn't defined in the DI
         */
        if !class_exists(name) {
            throw new Exception("Service '" . name . "' wasn't found in the dependency injection container");
        }

I want to use "di:beforeServiceResolve" change the parameters .

What should I do?

$di = new Phalcon\Di();
$eventsManager = new Phalcon\Events\Manager();
$eventsManager->attach('di:beforeServiceResolve', function(Event $event, Di $di, $data) {
// your logic
});

But im not sure you can change parameters "on the fly" using event manager. It's possible that you just need to extend phalcon di and override get method and do something with parameters and then call parent get.
