psr-4中的更多路径

Question

I'm learning namespaces and psr-4 autoloading. In my application I can load only the classes of the first object under psr-4 in composer.json.

I will explain better, this is my situation:

Folder Structure:

app
- core
-- Foo
--- Foo.php
src
- Bar
-- Bar.php

in composer.json

{
    "autoload": 
    {
        "psr-4":
        {
            "core\\"  : "app/core/",
            "myapp\\" : "src/"
        }      
    }
}

Only classes under app/core are loaded. If I use \\core\\Foo\\Foo works like a charm, but if I use \\myapp\\Bar\\Bar doesn't work. Of course I updated the autoload with composer dump-autoload -o and respected the Case Sensitive letters.

Where is my mistake? thanks in advance :-)

Answer 1

What is your current namespace in each of those files? According to your folder structure and setting in composer.json , these are the values you should have:

Bar\\Bar.php should have

<?php

namespace myapp\Bar;

class Bar {}

while

Foo\\Foo.php should have

<?php

namespace core\Foo;

class Foo {}

You should then be able to access them with new myapp\\Bar\\Bar and new core\\Foo\\Foo .

It's important that your filename and class name is the same.
