This error typically occurs in Laravel when a class or interface is not found by the autoloader. This means that Laravel attempted to locate the interface using the PSR-0(PHP Standards Recommendations) or PSR-4(PHP Standards Recommendations) autoloading standard, but couldn’t resolve the file path from the namespace. It can also occur if the file is included more than once or the service provider binding points to the wrong class name.
app/Multiplex/service/TheatreInterface.php
-> Use correct namespace inside the interface:
Namespace Multiplex\Service;
interface TheatreInterface {
public function createTicket($input, $book);
}
In MultiplexServiceProvider.php:
$this->app->bind(
'multiplex\service\TheatreInterface',
);
composer dump-autoload
php artisan clear-compiled
php artisan optimize
