pagination in your Symfony projects with the KnpPaginatorBundle

PHP

To list a large result set on your page can end up with long loading times and/or a confusing look. This is where pagination comes into play, it's a widely used concept to divide your content into clean blocks of data.

The KnpPaginatorBundle is a great bundle for pagination inside Symfony. The bundle requires Symfony >=3.4 and Twig >=2.0 if you use the twig templating engine in your project.

install KnpPaginatorBundle

The bundle can be installed using composer with the following command:

composer require knplabs/knp-paginator-bundle

If you don't use flex you have to register the bundle before you can use it.
