The productivity benefits of the PHP platform are well known.Its easy syntax, latent typing, high level of abstraction, and support for objects simplify and accelerate the production of large applications.Active record is an approach to accessing data in a database.” And admittedly, this definition accurately outlines the functionality of this pattern, even though it sounds hard to grasp at first.In many cases (though not all), implementing the active record pattern for a given web application requires the creation of a class instance that will be tied to each row of a database table.

A database query will be executed to retrieve each chunk of records passed to the Closure.
