When comparing CodeIgniter vs Silex, the Slant community recommends CodeIgniter for most people. In the question“What are the best PHP frameworks?” CodeIgniter is ranked 8th while Silex is ranked 13th. The most important reason people chose CodeIgniter is:
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 Well documented
The documentation is clear, structured and thorough. It explains both commonly used and CodeIgniter specific concepts and always with clear examples.
CodeIgniter has a small footprint, just 3MB and that's including the user guide.
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.
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 Open source
The MIT License (MIT)
CodeIgniter is open source and is distributed under the MIT license.
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 Built on top of Symfony components
The thing that makes Silex stand out from other PHP microframeworks is the fact that it's built using some of Symfony2's components. Making it quite powerful but still lightweight enough to be considered a true microframework.
Pro Open source
Silex is open source and is licensed under the MIT license.
Pro Simple and elegant DI container
Based on Pimple, Silex has a simple Dependency Injection container that consists of just one file and one class.
Silex makes use of Symfony2's HttpKernel which is used to abstract requests and responses. This in turn, makes it very easy to test apps created with the framework.
By using Pimple, the Silex application extends the Pimple class, which in turn is nothing more than an implementation of the ArrayAccess interface that has been a part of PHP since version 5.0.
This makes it possible to use an instance of the Application class as if it were an array. Like so:
$app = new Silex\Application(); $app['config'] = new Config($config_path);
This gives developers a great deal of flexibility when injecting dependencies and when testing.
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 not 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.
Con Documentation is not very extensive
The documentation for this framework is average, it's helpful mostly. But it is not extensive enough to cover everything in detail unfortunately.
