I suggest PHP CRUD Generator [Disclaimer: I'm the author]
PHPCG generates a Bootstrap 4 Admin Dashboard with CRUD Operations in a few clicks
PHP CRUD Generator is an easy-to-use Web Application for creating a complete Bootstrap 4 Admin Dashboard for any project using a MySQL database.
The application is separated into two parts: the CRUD Generator and the Admin Panel for the final user.
The CRUD Generator scans your database: structure, tables, fields and relationships.
All you have to do is select your options to create all the pages of the admin dashboard: lists of records, creation forms, editing forms, deletion forms.
The system is extremely complete and can be customized easily, allowing you to deal with any situation.
Lists can be filtered, the admin panel includes an authentication and user rights management module.
The full demo is available online. PHP CRUD Generator is sold at a ridiculously low price in comparison to the amount of work it will save you!
