Well, I confuse to start writing Yii Framework, should I write about definition, history, or about Framework? So, I think I have to write something important then theory so I decide to write about How to Installing Yii Framework in cPanel via Softaculous. Why using cPanel? Because in cPanel there are many feature that help you installing Yii Framework with easy way.

Okay, here we go ..

• First you have to do is login to your cPanel.
• Go to Software/Services and choose Softaculous (it's usually at the bottom of cPanel form). If your cPanel doesn't provide Softaculous, you can contact you hosting provider.

Picture 1. Softaculous

• Go to Frameworks and choose yii.

Picture 2. Yii Framework

• .Click the INSTALL button.

Congratulations, the software was installed successfully

A. Encapsulation

Figure 1 Implementing Encapsulation

B. Inheritance

<?php

class Parents {

public function helloParent() {

echo "This is parent class ...<br />";

}

}

class Child extends Parents {

public function helloChild() {

echo "This is child class ...<br />";

}

}

$objectChild = new Child();

$objectChild->helloParent();

$objectChild->helloChild();

?>

 If that script run, then this is looks like in browser :

Figure 2 Implementing Inheritance

There are two class appears in browser even we just create one class that’s because class Child inheritance from class Parent. Now we will continue about visibility protected in the previous tutorial, let’s modify class Parent and Child in the script above by adding one protected property in class Parent with name $name and one method in class child with name printParentName(). So this is the script :

Script 2. Implementing Inheritance with Protected Visibility
<?php
class Parents {
protected $name = 'Leonardo Da Vinci';
public function helloParent() {
echo "This is parent class ...<br />";
}
}
class Child extends Parents {
public function helloChild() {
echo "This is child class ...<br />";
}
public function printParentName() {
echo "Parent Name : $this->name <br />";
}
}

$objectChild = new Child();
$objectChild->helloParent();
$objectChild->printParentName();
$objectChild->helloChild();
?>

Property $name in parent class that using protected will run by method printParentName() in child class. When the script run then the name of parent class “Leonardo Da Vinci” will appear even the method run by child class. Look at the picture below :

Figure 3 Implementing Inheritance using Protected Visibility

It is proving that protected visibility can accessed via child class.

C. Polimorfism

Polimorfism is simple, in the previous tutorial you have used polimorfism. Polimorfism is a process creating one or more new object at some class. Let’s we reopen the script in previous tutorial, look at the script below :

Script 3. Implementing Polimorfism
<?php
class people {
private $name;
function __construct($name) {
$this->name=$name;
echo "Constructor : $this->name created <br>";
}
function speaking() {
echo "Hallo, my name is ".$this->name." <br />";
}
function __destruct() {
echo "Destructor : $this->name deleted <br/ >";
}
}
$people1 = new People("People 1");
$people1->speaking();
$people2 = new People("People 2");
$people2->speaking();

?>

Well, the text I colouring is polimorfism ....
