How to generate slug in laravel?

first add the Str class to your Controller:

use Illuminate\Support\Str;

Then use the Str::slug method and pass in your title:

$slug = Str::slug('Your Awesome Blog Title', '-');

$slug = Str::slug($request->title, '-');

After that, you can store this in your database and later on retrieve your posts by slug rather than ID for example:
$post = Post::where('slug', $slug)->firstOrFail();

File name : index.php

<?php
namespace App\Http\Controllers\admin;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Menu;
use DB;
use Illuminate\Support\Str;
class MenuController extends Controller
{

public function store(Request $request)
{

$request->validate([
'title' => 'required',
]);

$input = $request->all();
$input['parent_id'] = empty($input['parent_id']) ? 0 : $input['parent_id'];

// $slug = Str::slug($request->title, '-');
$input['slug'] = Str::slug($input['title'], '-');

Menu::create($input);
return back()->with('success', 'Menu added successfully.');
}

}
