After upgrading Laravel from 5.6 to 6.0, Call to undefined str_random() function not working
提问by Vishal Srivastava
I have upgraded Laravel from 5.6 to 6.0. Previously, default helper functions were running fine on the controllers, but now it says "undefined." In my controller, I have used the following.
我已将 Laravel 从 5.6 升级到 6.0。以前，默认的辅助函数在控制器上运行良好，但现在显示“未定义”。在我的控制器中，我使用了以下内容。
$filename = str_random(12);
I am getting the following error.
我收到以下错误。
message: "Call to undefined function App\Http\Controllers\str_random()"
消息：“调用未定义的函数 App\Http\Controllers\str_random()”
I have also used the random()function, and it's saying the same thing.
我也用过这个random()函数，它说的是同样的事情。
Can somebody please guide me on what to do?.
有人可以指导我做什么吗？

我已经运行了如下命令：
composer dump-autoload
But I get the same error.

Likelihood Of Impact: High Laravel 6 Upgrade Guide
影响的可能性：高Laravel 6 升级指南
In Laravel 6 All str_and array_helpers have been moved to the new laravel/helpersComposer package and removed from the framework. If desired, you may update all calls to these helpers to use the Illuminate\Support\Strand Illuminate\Support\Arrclasses. Alternatively, you can add the new laravel/helperspackage to your application to continue using these helpers:
在 Laravel 6 中 Allstr_和array_helpers 已移至新的laravel/helpersComposer 包并从框架中删除。如果需要，您可以更新对这些助手的所有调用以使用Illuminate\Support\Str和Illuminate\Support\Arr类。或者，您可以将新laravel/helpers包添加到您的应用程序以继续使用这些帮助程序：
composer require laravel/helpers
If don't want to add Package then Used StrAnd ArrClasses.
如果不想添加包然后使用Str和Arr类。
For Example :
例如 ：
Str::random(12)
回答by Hitendra Singh Shekhawat
Add the following string library.
添加以下字符串库。
use Illuminate\Support\Str;
now you can use it as below.
现在你可以使用它如下。
$filename = Str::random(40)
alternatively, install the following package.
或者，安装以下软件包。
composer require laravel/helpers
