Laravel Framwork

Laravel Framwork:

 Laravel PHP Framework is built with the focus of writing code syntax that is simple and expressive. This will provide the advantage of having a Web Application that is developer friendly and code that is maintainable.

Taylor Otwell created Laravel as an attempt to provide a more advanced alternative to the CodeIgniter framework, which did not provide certain features such as built-in support for user authentication and authorization.

It has been built with a focus of being superior over the other PHP frameworks, with better code foundation, maintainability and more robust features.

 When it comes to code reliability and maintainability, Laravel has a good foundation and great community support behind its PHP Framework.
