Questions tagged [symfony]

Symfony refers to both a PHP framework for building web applications as well as a set of components on which the framework is built. This tag refers to the currently supported major versions 3.x, 4.x, 5.x and 6.x. Alternatively, you can specify an exact version using the respective tag. This tag should not be used for questions about Symfony 1.x. Please use the Symfony1 tag instead.

Symfony is a framework for web and CLI-applications built on top of a catalogue of Symfony components. It is free software released under the MIT license. The project's homepage is symfony.com.

Symfony aims to speed up the creation and maintenance of web applications and replace repetitive coding tasks by providing a rich set of components and integrations for other libraries through bundles. It has a low-performance overhead used with a bytecode cache and is aimed at building robust applications in an enterprise context, and aims to give developers complete control over the configuration: from the directory structure to the foreign libraries. Almost everything can be customized. To match enterprise development guidelines, Symfony is bundled with additional tools to help developers test, debug and document projects. Most of the components making up the framework can be used outside of the framework in other projects and libraries.

Components

Besides being a full-stack framework, Symfony is also a set of decoupled and Components.

Some of the Components have their own tag:
