HomeBackend DevelopmentPHP TutorialLaravel框架中扩展函数、扩展自定义类的方法_php实例

一、扩展自己的类

在app/ 下建立目录 libraries\class 

然后myTest.php 类名格式 驼峰 myTest

复制代码 代码如下:

class myTest
{
public  function test()
{
return '1asdasd111';
}
}

在 app/start/global.php

复制代码 代码如下:

ClassLoader::addDirectories(array(
app_path().'/commands',
app_path().'/controllers',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/libraries/class', //增加这一段
));

用 make 载入
复制代码 代码如下:

class HomeController extends BaseController {
    protected $layout = 'layouts.main';
public function index()
{
$a = App::make('mytest'); // 用法
echo $a->test();
}
}

二、扩展自己的函数

在app/ 下建立目录 libraries\function

建立helper.php

函数格式,如下用function_exists,防止与系统重名

复制代码 代码如下:

if (! function_exists('test2'))
{
function test2()
{
echo 2222222222222222;
}
}

方法一:

在 app/filters.php

复制代码 代码如下:

App::before(function($request)
{
require app_path().'/libraries/function/helper.php'; //载入 自定义函数
});

方法二:

在app/bootstrap/autolad.php

复制代码 代码如下:

require __DIR__.'/../app/functions.php'; // 引入自定义函数库

我感觉方法一会比较好。
