Methods for extending functions and extending custom classes in the Laravel framework _ php instance

This article mainly introduces the methods of extended functions and extended custom classes in the Laravel framework. It is a very practical technical article. For more information, see 1. Expand your class

Create the libraries \ class directory under app /.

Then myTest. php class name format camper myTest

The Code is as follows:

<? Php
Class myTest
{
Public function test ()
{
Return '1asdasd111 ';
}
}

In app/start/global. php

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 section
));

Load with make

The Code is as follows:

<? Php
Class HomeController extends BaseController {
Protected $ layout = 'layouts. main ';
Public function index ()
{
$ A = App: make ('mytest'); // usage
Echo $ a-> test ();
}
}

2. Expand your own functions

Create the libraries \ function directory in app /.

Create helper. php

Function Format. Use function_exists as follows to prevent duplicate names with the system.

The Code is as follows:

If (! Function_exists ('test2 '))
{
Function test2 ()
{
Echo 2222222222222222;
}
}

Method 1:

In app/filters. php

The Code is as follows:

App: before (function ($ request)
{
Require app_path (). '/libraries/function/helper. php'; // load custom functions
});

Method 2:

In app/bootstrap/autoglad. php

The Code is as follows:

Require _ DIR _. '/../app/functions. php'; // introduce the custom function library

I think the method will be better.
