使用命名空间并在php / laravel中使用？

Question

I have two files in the same directory Graph:

IModel.php

DataModel.php

For these files in the top I set namespace as: namespace App\Library\Graph;

When I try to use IModel.php in DataModel.php I do:

namespace App\Library\Graph;

use IModel;

I get response: Interface 'IModel' not found

Answer 1

You need to include the php file and then you will be able to call the class.

require('App\Library\Graph\IModel.php');

$myClass = new IModel();

You can also use an autoloader.. Then include the autoloader and all your classes that are mapped through the autoloader will be able to be called.

Here is a link to read about autoloading using composer.
