What are Hooks in CakePHP?

Hooks in Cakephp are nothing but the functions that are called prior or after doing any task in the models related to the database. These are the callback functions like after finding data, before saving data, etc. Some example for this method are beforeSave(), afterSave(), beforeFind(), afterFind(), etc.

Example

<?php
class Classname extends AppModel {
    var $name = "Classname";
   public function beforeSave(){
        // your code
    }
   public function afterSave(){
        // your code
    }
}   
?>
