HOW TO INSTALL

composer req phlllpe/chain

USAGE

• Create a Handlers, example:

namespace Any\Handler;

use Chain\AbstractHandler;
use Chain\ContextInterface;

class MyHandler extends AbstractHandler 
{
    public function handle(ContextInterface $context)
    {
        // TO DO ANY ACTION HERE, WITH ANY TEST
        if ($context->get('any') == 'HERE') {
            $context->set('myClass', static::class);
        }
        
        return parent::handle($context);
    }
}

• Define a sequence to setup/analyse your context with your handlers;

namespace Any\Service;

use Chain\Context;
use Any\Handler\{
    MainHandler,
    AddressHandler,
    BudgetHandler,
    FamilyHandler
};

class MyService
{

    public function __invoke()
    {
        $context = new Context();
        $context->set('name', 'Philipe Fernandes');
        
        $mainHandler = new MainHandler();
        $addressHandler = new AddressHandler();
        $budgetHandler = new BudgetHandler();
        $familyHandler = new FamilyHandler();
    
        $mainHandler
            ->setNext($addressHandler)
            ->setNext($budgetHandler)
            ->setNext($familyHandler)
            
        (new Runner())->run($mainHandler, $context);
    }
}
