如何包含扩展接口的php类

Question

I'm developing a socket listener that has to process data with CommandService class.

CommandService.php

<?php
namespace Application\Service;

use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorAwareTrait;

class CommandService implements ServiceLocatorAwareInterface
{
    use ServiceLocatorAwareTrait;

} 

custom.php

<?php
include('../module/Application/src/Application/Service/CommandService.php');
?>

And when I run on console

php custom.php

I get error: Fatal error: Interface 'Zend\ServiceManager\ServiceLocatorAwareInterface' not found in C:\wamp\www utirent\module\Application\src\Application\Service\CommandService.php on line 7

So I't would be great if someone can give me some advice how can I get this running without making custom.php as class.

Answer 1

If you are not using any automated loading system (i.e. composer's autoloader) then its your responsibility to load all the dependencies.

So in this case just loading the CommandService is not enough and you also need to load (include) Zend\ServiceManager\ServiceLocatorAwareInterface as well as all the other dependencies :)

So I would strongly suggest to consider using an autoloader ;)
