“Call to undefined function str_slug()” in Laravel 6.0

问题

I've upgraded my laravel 5.8 project to 6.0. It has upgraded successfully but when I'm trying to run the project or installing another package to my project it is giving me error named as "Call to undefined function str_slug()" in session.php. I don't know why....

Call to undefined function str_slug()

回答1:

If you have gone through the upgrade guide then you must know that

String and Array

Helpers are removed from Core Framework

https://laravel.com/docs/6.0/upgrade#helpers

https://github.com/laravel/framework/blob/5.8/src/Illuminate/Support/helpers.php#L1071

So if if You need to still use the helper install the package

composer require laravel/helpers

and all the helpers are moved to this package

composer require laravel/helpers

Or you can use by Laravel facade

use Illuminate\Support\Str;
$slug = Str::slug('Laravel 5 Framework', '-');

Personal I hard to do the following on Laravel 6 on the app Controllers add this use Illuminate\Support\Str; then something like this 'slug' => Str::slug($request->title)
