Extension functions and methods of extending custom classes in Laravel framework, laravel framework

1. Extend your own class

Create a directory librariesclass under app/

Then myTest.php class name format camel case myTest

Copy code The code is as follows:

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

in app/start/global.php

Copy code The code is as follows:

ClassLoader::addDirectories(array(
app_path().'/commands',
app_path().'/controllers',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/libraries/class', //Add this paragraph
));

Load with make

Copy code The code is as follows:

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

2. Extend your own functions

Create the directory librariesfunction under app/

Create helper.php

Function format, use function_exists as follows to prevent duplication of names with the system

Copy code The code is as follows:

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

Method 1:

In app/filters.php

Copy code The code is as follows:

App::before(function($request)
{
require app_path().'/libraries/function/helper.php'; //Load custom function
});

Method 2:

In app/bootstrap/autolad.php

Copy code The code is as follows:

require __DIR__.'/../app/functions.php'; //Introduce custom function library

I think the first method is better.
