Create a PHP template

I want a php code template that allows me to create any web application that needs business logic and access to modify or create records in a MySQL database. Also this template should be ready to use email if I need to send emails to my users automatically. It is desirable that this template be designed with at least some patterns or frameworks to ensure quality in developments. Keep in mind so it has to be very descriptive through a guide, so any of my developers could understand it and start any kind of project very quickly.
