【PHP】composer使用笔记

laravel 全局函数文件配置（摘抄）

An easy and efficient way of creating a global functions file is to autoload it directly from Composer. The autoload section of composer accepts a files array that is automatically loaded.

Create a functions.php file wherever you like. In this example, we are going to create in inside app/Helpers.

Add your functions, but do not add a class or namespace.

<?php

function global_function_example($str)
{
   return 'A Global Function with '. $str;
}

In composer.json inside the autoload section add the following line:

"files": ["app/Helpers/functions.php"]
Example for Laravel 5:

"autoload": {
    "classmap": [
        "database"
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "files": ["app/Helpers/functions.php"] // <-- Add this line
},

Run composer dump-autoload

Done! You may now access global_function_example('hello world') form any part of your application including Blade views.
