Laravel 5.3 : How to inject variables into "layout" page?

Laravel 5.3 : How to inject variables into "layout" page?

I tried "Service Injection" , like this:

@inject('siteInfo', 'App\Services\SiteInformation')
    <title>{{ $siteInfo->name }}</title>
    <meta name="keywords" content="{{ $siteInfo->keywords }}"/>
    <meta name="description" content="{{ $siteInfo->description }}"/>

SiteInformation.php 

<?php

namespace App\Services;

use App\SiteInfo;


class SiteInformation
{

    public $siteInfo;

    public function __construct() {

        $this->siteInfo = SiteInfo::all();

    }
}

error: 

Undefined property: App\Services\SiteInformation::$name (View: D:\wnmp\www\laravel-5-3-dev\resources\views\layouts\app.blade.php)

Questions:

1.How could I modify the code?
2.Are there any other ways to do it?

Edit:

And I tried another way in AppServiceProvider.php 

public function boot()
{
    view()->composer('layouts/app', function ($view) {
        $siteInfo=SiteInfo::all();
        dd($siteInfo);
        $view->with('siteName',$siteInfo->name)   // this is line 22
            ->with('siteKeywords',$siteInfo->keywords)
            ->with('siteDescription',$siteInfo->description);
    });
}

The error is the same: 

ErrorException in AppServiceProvider.php line 22:
Undefined property: Illuminate\Database\Eloquent\Collection::$name (View: D:\wnmp\www\laravel-5-3-dev\resources\views\pages\index.blade.php)

The location of line 22 has comment in AppServiceProvider.php.

The result of dd($siteInfo);:

SiteInfo::all() returns a collection of rows, here it has only one row.

So you could do:

$rows = SiteInfo::all();
$siteInfo = $rows->first();

But better, just use Eloquent's method:

$siteInfo = SiteInfo::first();

Indeed $name property does not exist. Try:

@inject('siteInfo', 'App\Services\SiteInformation')
<title>{{ $siteInfo->siteInfo->name }}</title>

or if it is an array:

<title>{{ $siteInfo->siteInfo['name'] }}</title>

Edit

Based in your print, try to get a single item instead a collection:

public function __construct() {

    $this->siteInfo = SiteInfo::first();

}

Then you should be able to do:

<title>{{ $siteInfo->siteInfo->name }}</title>
