Cakephp-Overview of Programming Patterns

Active Record Pattern

Active Record Pattern is for those application's which use relational databases.
The interface of an object conforming to this pattern would include functions such as Insert, Update, and Delete, plus properties that correspond more or less directly to the columns in the underlying database table.

Association Data Mapping

An Association data mapping pattern allows Relational object to associate with other Relational Objects the way they are associated in Relational Databases.

Front Controller

Model's act as a wrapper classes for Database Table's
Controller's act as wrapper classes for Business Logic
and View act's as file for User Interface
 

OOPS-PHP-Magic Methods

1. __get($property)

Get value for a property set in a class foe example

 function __get($property)  
 {  
 return $this->properties[$property];  
 }  

Usage: echo $st->name;

2. __set($property,$value) Set value for a property

 function __set($property, $value)  
 {  
 $this->properties[$property]="AutoSet {$property} as: ".$value;  
 }  

Usage: $st->roll=16;

3. __call()
overloads any undefined function in a class.Thus we can also call an undefined function and show custom error message.

 function __call($method, $arguments)  
 {  
 echo "You called a method named {$method} with the following  
 arguments <br/>";  
 print_r($arguments);  
 echo "<br/>";  
 }  

Usage: $ol->notAnyMethod("boo");

OOPS-What is the difference between Static and Final Keyword

Static
A static method remains common for all objects and can be called directly without the need of creation of any object.

For Example : classname::functionname();

A static property on the other end remains common for all the objects.It preserves its last changed state by any object.

Final
Final keyword on other end does not allows a class to be extended a method to be overridden in subclass or to change a property respective to its use in a class.

OOPS-PHP-usefull functions

1. get_declared_classes();
Returns an array with the name of the defined classes.Useful when you have integrated a component or helper or vender class and what to know whether it's been included or not.
