Laravel 9 Tutorial: Laravel 9 new features
With the different features of Laravel, it is the most favorite framework amongst developers and companies using the PHP programming language. This adoption is due to the elegancy and scalability nature of the framework.
With the Laravel 9 release, the Laravel team switches from the traditional 6-month release cycle to a 12-month release cycle using the Semantic Versioning(Semver) approach.
The initial schedule of the Laravel 9 release was supposed to be September 2021, following the traditional approach. Still, the release date changed to January 2022 as stated by the creator and with a few valid reasons, as noted below.
In this article, we will discuss in detail Laravel 9 and the best features of Laravel. We will also detail how to update or upgrade to Laravel 9 and install and start building an app with the new Laravel 9.

Laravel is an open-source PHP web application framework with expressive, elegant syntax. It is an MVC framework for building simple to complex web applications using the PHP programming language.
Laravel strictly follows the MVC (Model-View-Controller) architectural pattern. It is known for its beautiful and elegant syntax as a web framework.
If you haven’t used Laravel, you can read through the ultimate guide to Laravel and peek at Laravel 8 new features to get started.
Laravel 9 is the first Long Term Support (LTS) released in a 12-month release cycle and was initially scheduled to be released by September 2021; however. The Laravel team decided to push it to January 2022.
This release schedule is due to these reasons outlined below: with these reasons below, the release date was pushed forward.
- Laravel as a framework relies on different community-driven and 9 Symfony libraries, and Symfony is planning to release v6.0 by November 2021, making the Laravel team delay release of Laravel v9.
- To update or upgrade the entire Laravel framework to the latest version of Symfony will take a while and also lots of testing and monitoring against any breaking changes before releasing it to the public.
- Finally, delaying the release of Laravel 9 till January 2022 will better position the Laravel team to release subsequent LTS yearly which gives the Laravel team 2 months after Symfony’s releases.
Now that we know the reasons for the changes, let’s explore the new Laravel v9 before it is released by January 2022.
Below is the newest features and improvement that we should expect in the Laravel v9 by January 2022:
Laravel 9 requires the newest version of PHP 8, PHPUnit 9, and a few other requirements specified in the future.
The PHP 8 requirement is because Laravel 9 is solely dependant on Symfony’s latest v6.0 release, which depends on PHP 8.
You can explore what is new in PHP 8 and the different PHP versions benchmarks to grasp the improvements and features of PHP 8 from Just-In-Time compiler (JIT) to constructor property promotion.
The anonymous stub migration released in Laravel version 8.37 to solve this Github Issue will be the default behavior of the newest Laravel 9.
Anonymous Stub Migration eliminates the collision of migration class names. The collision happens when multiple migrations have the same class name, it’ll cause issues when trying to recreate the database from scratch.
Here is the sample code snippet of how the new migration file will look like:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration {
/** * Run the migrations.
*
* @return void
*/
public function up() {
Schema::table('users', function (Blueprint $table) {
$table->string('first_name')->nullable();
});
}
};This code snippet uses Schema::table instead of the traditional Schema::create() method.
Type hinting is crucial as developers highly rely on refactoring, static analysis, and code completion in their IDEs.
With Laravel 9, developers can now enjoy a shared interface or inheritance between Query\Builder, Eloquent\Builder and Eloquent\Relation with the new Query Builder Interface.
You can read through this for all the details:
<?php
return Model::query()
->whereNotExists(function($query) {
// $query is a Query\Builder
})
->whereHas('relation', function($query) {
// $query is an Eloquent\Builder
})
->with('relation', function($query) {
// $query is an Eloquent\Relation
});Laravel v9 added the new Illuminate\Contracts\Database\QueryBuilder interface and Illuminate\Database\Eloquent\Concerns\DecoratesQueryBuilder trait that will implement the interface in place of the existing __call magic method.
Laravel v9 requires PHP v8, so the Laravel team agreed to merge a PR to use the newest PHP 8 String functions.
The suggested functions include str_contains(), str_starts_with() , and str_ends_with() to be used internally in the \Illuminate\Support\Str class.
Laravel v9 is still in active development and will introduce more future improvements and features that we have not listed yet in this article. Laravel v9 will most definitely come with lots of significant changes, bug fixes, features, and of course, many breaking changes.
