未找到 Composer 自动加载类 [英] Composer Autoloading classes not found

问题描述

我的文件夹结构如下:

includes/
  libraries/
    Classes/
      Contact/
        Contact.php
        ContactController.php

admin/
  controllers/
    contact/
      edit.php

Contact.php 是我尝试使用的那个文件的类.该文件包含.

Contact.php is my class that file that I'm trying to use. The file contains.

<?php
namespace Classes;

class Contact {
    function __construct() {
        die('here');
    }
}

我的 composer.json 文件如下:

I have my composer.json file like:

{
    "autoload": {
        "psr-4": {
            "Classes\": "includes/libraries/Classes/"
        }
    },
}

我试图在其中使用 Contact 类的文件是 admin/controllers/contact/ 文件夹中的 edit.php.我的 edit.php 文件就像:

The file I'm trying to use the Contact class in is edit.php within the admin/controllers/contact/ folder. My edit.php file is like:

<?php

use ClassesContact;

$contact = new Contact();

var_dump($contact);

此文件包含 vendor/autoload.php 文件，但我似乎无法让它使用该类?

This file has the vendor/autoload.php file included, yet I can't seem to get it to use the class?

推荐答案

Classes/Contact/Contact.php 和作曲家规则 "Classes\": "includes/libraries/Classes/" 表示 ClassesContactContact 类，而不是 ClassesContact.

Classes/Contact/Contact.php and the composer rule "Classes\": "includes/libraries/Classes/" imply ClassesContactContact class, not ClassesContact.

因此，如果您确实需要 ClassesContact 类，请将 Classes/Contact/Contact.php 文件移至父目录:Classes/Contact.php.

So if you actually want ClassesContact class, move the Classes/Contact/Contact.php file up to the parent directory: Classes/Contact.php.

但是，如果类的所需命名空间路径是ClassesContactContact，则更改use:

If, however, the desired namespace path to the class is ClassesContactContact, then change the use:

use ClassesContactContact;

还有命名空间:

namespace ClassesContact;

class Contact {}

示例

├── composer.json
├── includes
│   └── libraries
│       └── Classes
│           └── Contact
│               └── Contact.php
├── test.php
└── vendor
    ├── autoload.php

        ├── autoload_static.php
        ├── ClassLoader.php
        ├── installed.json

vendor/下的文件由composer生成.

The files under vendor/ are generated by composer.

composer.json

{
    "name": "testpsr4",
    "autoload": {
        "psr-4": {
            "Classes\": "includes/libraries/Classes"
        }
    }
}

test.php

<?php
require_once __DIR__ . '/vendor/autoload.php';

use ClassesContactContact;

$c = new Contact;
$c->test();

includes/libraries/Classes/Contact/Contact.php

<?php
namespace ClassesContact;

class Contact {
    public function test () {
        echo __METHOD__, PHP_EOL;
    }
}

测试

composer update
php test.php

输出

ClassesContactContact::test
