Basci : No.Of Patters in PHP

There are 23 different known design patterns, and they can be separated into three categories by purpose:

• Creational Patterns: used to construct objects such that they can be decoupled from their implementing system
• Structural Patterns: used to form large object structures between many disparate objects
• Behavioral Patterns: used to manage algorithms, relationships, and responsibilities between objects
