Datatypes in PHP - Objects : Tutorial

6. Object datatype

Objects are Compound data types.

An Object can hold a collection of datatypes. We can create our own datatypes using Object datatype

is_object() function is used to test whether a variable is an object instance.

Example :

<?php

class MyDetails {

	private $name;
	private $age;
	private $message;


	function getName() {
		echo "Name : ".$this->name ."<br/>";
	}

	function setName($name) {
		$this->name = $name;
	}


	function getAge() {
		echo "Age : ".$this->age ."<br/>";
	}

	function setAge($age) {
		$this->age = $age;
	}



	function setMessage($message) {
		$this->message = $message;
	}
	
	function getMessage() {
		echo "Message : ".$this->message ."<br/>";
	}

}

//Object Datatype
$myDetails = new MyDetails;

//Calling Setter Functions
$myDetails->setMessage("I love PHP!");
$myDetails->setAge("19");
$myDetails->setName("Mike");

//Calling Getter Functions
$myDetails->getName();
$myDetails->getAge();
$myDetails->getMessage();

?>

Output
	

Name : Mike
Age : 19
Message : I love PHP!

Note :

Objects is an Advance topic, it is covered in details after learning Functions.
