作曲家自动加载PSR-0找不到类

Question

This is my project structure

api
 |
 PicoApi
    |
     managers
             |
              ApiManager.php
     composer.json     
 index.php

This is how my composer looks like:

{
    "autoload": {
        "psr-0": {
            "PicoApi\\": "",
            "PicoApi\\Managers\\" : "managers"
        }
    }
}

This is my index.php:

//require Pico Api autoload
require 'vendor/autoload.php';

use PicoApi\Managers\ApiManager;

try {
    //initialize the API
    ApiInitializer::initialize();

    //initialize a new Api with the request
    $api = new ApiManager($_REQUEST['request']);
    echo utf8_encode($api->processApi());

} catch (Exception $e) {
    echo json_encode(Array(Error::jsonErrorField() => $e->getMessage()));
}

in my ApiManager.php I included: namespace PicoApi\\Managers;

And yet i get an error that it doesn't find ApiManager.php.

When changing the composer to psr-4 it does work, but I want it to be psr-0.

What am I doing wrong ?

Answer 1

You are using the notation PSR-4 , so you need to use PSR-4. PSR-0 does not allow for an intercessory path between any portions of the class name. If you want use it you need move src/managers/ApiManager.php in src/PicoApi/Managers/ApiManager.php then

"psr-0": {
    "PicoApi\\": "src"
}
