FluentInterface

Fluent Interface

Purpose

To write code that is easy readable just like sentences in a natural language (like English).

Examples

• Doctrine2's QueryBuilder works something like that example class below
• PHPUnit uses fluent interfaces to build mock objects
• Yii Framework: CDbCommand and CActiveRecord use this pattern, too
