How import custom class in controller Laravel?
提问by Dev
I have created a new directory Libraryin root of Laravel.
我Library在 Laravel 的根目录中创建了一个新目录。
Inside I put the file with class:
在里面我把文件放在类中：
class My {
//
}
class My {
//
}
So, in controller Laravel I try to get access to this class:
因此，在控制器 Laravel 中，我尝试访问此类：
App\Library\My
But Laravel does not determine this path.
但是 Laravel 并没有确定这条路径。
This is my code:
这是我的代码：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use View;
use App\Library\My;
class HomeController extends Controller
{
//
}

As above, make sure it is placed in the App directory and make sure it is properly namespaced e.g.
如上，确保它被放置在 App 目录中，并确保它被正确命名，例如
<?php
$fOne = new \App\library\functions;
$isOk = ($fOne->isOk());
?>

You have to properly namespace your every class.
你必须正确命名你的每个类。
So you can import your class with usekeyword, like so
所以你可以用use关键字导入你的类，就像这样
use App\Library\My;
....
$my = new My();
Or if you've conflicting class name then you can use askeyword to alias the classname while importing
或者，如果您有冲突的类名，那么您可以as在导入时使用关键字为类名设置别名
use App\Library\My as MySecond;
....
$my = new MySecond();
And if you want to directly access your class within the method then you can access it like so.
如果你想在方法中直接访问你的类，那么你可以像这样访问它。
$my = new \App\Library\My();
Note:The leading \means App was declared in the global scope.
注意：领先\意味着 App 是在全局范围内声明的。

You should create Libraryfolder inside appfolder
您应该Library在app文件夹内创建文件夹
namespace App\Library\My
namespace App\Library\My
appfolder is alrdy used psr-4
app文件夹已被使用 psr-4
In your controller
在您的控制器中
use App\Library\My as My
use App\Library\My as My
It's work for me. Hope this answer is helpful
