Laravel 4.2：在控制器中包含一个PHP文件(库)

然后在您的composer.json文件中,您可以在自动加载类图中包含app / libraries：

{
    "name": "laravel/laravel","description": "The Laravel Framework.","keywords": ["framework","laravel"],"license": "MIT","require": {
        "laravel/framework": "4.2.*",},"autoload": {
        "classmap": [
            "app/commands","app/controllers","app/models","app/libraries",<------------------ YOUR CUSTOM DIRECTORY
            "app/database/migrations","app/database/seeds","app/tests/TestCase.php"
        ]
    },"scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled","php artisan optimize"
        ],"post-update-cmd": [
            "php artisan clear-compiled","post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },"config": {
        "preferred-install": "dist"
    },"minimum-stability": "stable",}

确保在修改composer.json后运行composer dump-autoload.

假设您的类名称为CustomClass.php,它位于app / libraries目录中(因此完整路径为app / libraries / CustomClass.php).如果按照惯例对类进行了正确命名,则命名空间可能会命名为库.为了清楚起见,我们将调用我们的命名空间自定义以避免与目录混淆.

$class = new customCustomClass();

或者,您可以在app / config / app.php文件中为其指定别名：

/*
|--------------------------------------------------------------------------
| Class Aliases
|--------------------------------------------------------------------------
|
| This array of class aliases will be registered when this application
| is started. However,feel free to register as many as you wish as
| the aliases are "lazy" loaded so they don't hinder performance.
|
*/

'aliases' => array(
    ...
    'CustomClass'   => 'customCustomClass',...
)

您可以像应用任何其他类一样在应用程序的任何位置实例化该类：

$class = new CustomClass();

希望这可以帮助！
