Upgrading Laravel from 5.5 -> 5.6

Notes on Upgrading Laravel from 5.5 -> 5.6

Start by creating a new upgrade branch from the master branch:

git checkout –b laravel-5.5-upgrade –master

Next Purchase a Laravel shift using this new upgrade branch name

Merge the branch that is created by Laravel shift into this new upgrade branch

Git fetch origin
Git checkout shift-42238
Git checkout laravel-5.5-upgrade
Git merge shift-42238

Now its time to check how the site is doing on our local machine, but first we will want to update composer & clear config, route & view caches:

composer update
php artisan cache:clear
php artisan route: clear
php artisan view:clear

Now it’s time to fix any errors that cop up, our first error is:

array_keys() expects parameter 1 to be array, integer given

Solution: in app -> Http -> Middleware -> TrustProxies.php set the following:

protected $headers = [
    Request::HEADER_FORWARDED => 'FORWARDED',
    Request::HEADER_X_FORWARDED_FOR => 'X_FORWARDED_FOR',
    Request::HEADER_X_FORWARDED_HOST => 'X_FORWARDED_HOST',
    Request::HEADER_X_FORWARDED_PORT => 'X_FORWARDED_PORT',
    Request::HEADER_X_FORWARDED_PROTO => 'X_FORWARDED_PROTO',
];

our second error is: Class user not found. To fix this we update config -> auth.php to the following:

'model' => App\Models\User::class,
