自建了 php autoload ，並同時使用 composer 的 autoload，應該注意什麼？

不知道大家有沒有看過下面的 php autoload 教學？

Eric G. Huang 不像樣工程師
PHP系列 – Autoload 自動載入

跟據這個教學，我解決了很多 class include require 檔案引入的困難，而且用了很長時間。

下面提供一些參考資料，讓大家可以分享。

運用Composer Autoloader

1. 準備自建的 namespace 和 目錄位置

e.g. 
namespace1 = application\control\, 目錄位置 = {user_directory}/application/control 
namespace2 = application\module\, 目錄位置 = {user_directory}/application/module 
namespace3 = application\mouule\sql\, 目錄位置 = {user_directory}/application/module/sql
Class 例子：

<?php
//application/module/config.php

namespace application\module;

class config
{


    function __construct() {
        ...
    }
}

2. 在 composer.json 加入自建的 namespace 和 目錄位置

{
    "autoload": {
        "psr-4": {
            "application\\control\\": "application/control/",
            "application\\module\\": "application/module/",
            "application\\module\\sql\\": "application/module/sql/"
        }
    }
}

3. 進入 console mode，使用用戶權限及用戶的root目錄，執行下面的程式

composer dump-autoload

4. 在需要的php 程式中，頂部加入(因為我的 composer 是放在 /vendor中，請自行改進)

require __DIR__ . '/vendor/autoload.php';
