Ranked in these QuestionsQuestion Ranking
Pros
Pro Good for building RESTful APIs
With migrations, powerful and intuitive Eloquent CRUD, resource routing, and simple JSON response out of the box, a complete REST API can be written in hours.
Pro Comes with an excellent built-in ORM
Laravel's Eloquent ORM is a simple and fast Object-Relational Mapping which helps with organizing the application's database. It supports the most popular databases (MySQL, Postgres, SQLite, etc.) out of the box.
Pro Good documentation
Laravel's documentation is thorough and very good. It covers everything and is very helpful to experienced and new users alike.
Pro Handles event queuing
Laravel supports event queuing and it does so in a very simple way. To create an event that should be queued just run:
php artisan handler:event SendPurchaseConfirmation --event=PodcastWasPurchased --queued
This creates a handler that implements the Illuminate\Contracts\Queue\ShouldBeQueued
interface. Now when this handler is called it will automatically be queued by the event dispatcher.
Pro Comes with its own CLI
Laravel comes out of the box with it's own CLI called Artisan. With Artisan developers can do several different tasks such as migrating databases, seeding databases, clearing the cache and much much more.
Pro Easy to write web apps with authentication
Laravel comes with Authentication capabilities and a fully-powered Auth class out of the box. For passwords it uses bcrypt.
Pro Easy to learn
Pro Gives developers a great degree of freedom in how they set up their project structure
Laravel allows for free configuration and does not force developers to use a single project structure, instead they can change it to how they wish.
Pro Can use Symfony components
Laravel uses many libraries built for the Symfony PHP framework. Many of these libraries are well-built and have been tested by users before. Since the point of using a web framework is to shorten development time and to avoid reinventing the wheel for problems that have already been solved, then it's logical for a framework to use libraries already built to solve problems that have already been solved.
Pro Extremely powerful template system
Laravel has a powerful template system called Blade. It's quite similar to Twig or Moustache with lots of curly braces but the real power comes from the usage of PHP code directly in the view. Blade templates compile directly to raw PHP and are processed in the server when a request is made.
Pro Gulp tasks in the form of Laravel Elixir
In Laravel 5.0 they added Laravel Elixir, which provides an API for using Gulp tasks for Laravel applications. Elixir supports several CSS preprocessors and even some test tools. But it's still in the early stages of development and it will be developed even further in the following releases. With more methods and more Gulp tasks supported.
Pro Great Ecosystem
Has a great Ecosystem with SAAS like: Forge, Envoyer, Nova & from 3rd parties like oh-dear
Pro Great Community
Pro Beginner-friendly
Setting up CodeIgniter is quick and easy. You can download the version you want from the CI homepage or directly pull the latest version from GitHub. After that, you unzip the contents to the directory that's required. The final step is to edit the config.php
to suit your needs and it's set up and ready for development.
There are also a lot of guides and tutorials from developers who have been using CI for a long time. This is because of the relative old age of the framework and the large community behind it.
Pro Lightweight
CodeIgniter has a small footprint, just 3MB and that's including the user guide.
Pro Well documented
The documentation is clear, structured and thorough. It explains both commonly used and CodeIgniter specific concepts and always with clear examples.
Pro Active community
Because it's relatively old and well-liked, it has an active community of developers behind it. It's used by a lot of websites in production.
Pro Open source
The MIT License (MIT)
CodeIgniter is open source and is distributed under the MIT license.
Pro Stable
CodeIgniter is tested by hundreds of thousand of developers that use it in production. This means that it's very hard for any bugs or problems to go unnoticed. Even when a new version is out, bugs are quickly found and patched up.
Pro Easy to use templating engine
CodeIgniter has it's own templating engine built-in. It's based on a mustache-like templating language which is easy to learn for new developers who have never seen it. While experienced developers will feel very comfortable using it.
Pro Output caching
CodeIgniter lets you cache the web pages in order to decrease loading times and increase efficiency and performance.
Pro CodeIgniter v4 is a complete rewrite
CI4 will be out soon & is a rewrite..
"CodeIgniter 4 is a rewrite of the framework and is not backwards compatible."
So it will support ALOT more newer functionality built-in.
Cons
Con Uses too much magic methods
It complicates debugging and autocompletion.
Con Bloated
While the speed doesn't seem to be an issue with it (on local tests), in production it may be hindered. The framework creates a ton of files and folders, some of which your app might not even use. Not good if you don't like having a ton of folders and rigid non-standard PHP folder structure for development.
Con Hard to use model properties
You need to check all model properties in database to know it exists, or declare all them manually.
Con Steep learning curve
While a lot of times you can write things in plain PHP, it will hinder you down the line when you want to use core features and find that you have to rewrite code which then causes issues throughout the app. Documentation is good, but you need to know what you are looking for and practical examples are non-existent. Many features have been updated throughout the versions in such a short time that tutorials you find online are confusing to sort through outdated tutorials and guides that no longer work or have been depreciated.
Con Poor performance
Con Follows bad design practices
Uses bad practices, like Singletons, Magic models, Middleware.
Con Outdated
CodeIgniter was first released during the times of PHP 4. This means that a lot of features that were added later to PHP are not available. Some of these features are:
- Support for namespaces
- Modular separation by default
- Procedural function helpers
While nowadays CodeIgniter can be used along the latest version of PHP, these features were not added so as not to mess with backward compatibility. They can still be used with CI, but it requires extending core files to make it work which is a waste of time and energy and requires advanced knowloedge of both PHP and CI.
Con No unit testing
Con It does not have basic functions
Some of the missing features include controller security, filters in forms and modoles, rules of validation, among others.
