Reef - the Responsive Embeddable Extensible Form generator for PHP

Reef is a form generator written in PHP. It provides functionality to let your users build forms that can in turn be filled in by other users. It provides support to create, modify and delete forms. Forms can also be modified after submissions have been received. It is framework agnostic, in the sense that Reef is not built on top of or using a PHP framework. Hence, it can be used in combination with any framework.

Users can build forms using a drag and drop user interface. The forms and submissions are stored in your database using PDO. You can generate HTML code for displaying submissions, and also generate a CSV file containing all submissions.
