1.Define the following terms with simple PHP snippet codes. You don’t have to write the entire code and compile, but the code should use correct syntax. (For example, don’t leave a ; out at the end of the line or not have a $ sign before the variable).
-Inheritance
-Polymorphism
-Encapsulation

2.Use an interface or abstract class program and customize it using your creativity to show the usage of Interface or Abstraction in PHP language. Make sure you have a good program purpose which gives a good description of the program.

Solution

1.) Inheritance -Inheritance is a well-established programming principle, and PHPmakes use of this principle in its object model. This principle will affect the way many classes and objects relate to one another.

class HTML
{
protected $name;
public $id;
private $with;
protected function basicAttribute
{
return \"name=\'$this->name\' id=\'$this->id\'\";
}
}
Class HTML_div extends HTML
{
public function __construct($id , $name)
{
$this->id = $id;
$this->name = $name;
}

Polymorphism -polymorphism is the ability to appear in different forms. Technically, it is the ability to redefine methods for derived classes. Poly means many and morphism means forms.

Encapsulation - Encapsulation is just wrapping some data in an object. The term \"encapsulation\" is often used interchangeably with \"information hiding\".

2.)

<?php
abstract class AbstractClass
{
    // Force Extending class to define this method
    abstract protected function getValue();
    abstract protected function prefixValue($prefix);

    // Common method
    public function printOut() {
        print $this->getValue() . \"\ \";
    }
}

class ConcreteClass1 extends AbstractClass
{
    protected function getValue() {
        return \"ConcreteClass1\";
    }

    public function prefixValue($prefix) {
        return \"{$prefix}ConcreteClass1\";
    }
}

class ConcreteClass2 extends AbstractClass
{
    public function getValue() {
        return \"ConcreteClass2\";
    }

    public function prefixValue($prefix) {
        return \"{$prefix}ConcreteClass2\";
    }
}

$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue(\'FOO_\') .\"\ \";

$class2 = new ConcreteClass2;
$class2->printOut();
echo $class2->prefixValue(\'FOO_\') .\"\ \";
?>
