Object oriented programming in PHP

[softwarefreak]

Hi guys,I was trying to figure out the advantages of OOP in php,but still not getting a good reason to make it use in real work.

Wat I'm trying to say is,

class introduceYourself

{
private $_name;

public function __construct($name)
{
$this->_name = $name;
}
public function writeName()
{
echo 'My name is ', $this->_name, .'<br />';
}
}

$intro = new introduceYourself("someone");
$intro->writeName();
///////////////////////////////////
output://////////////////////////
My name is someone///////////
///////////////////////////////// 

Can someone demonstrate a superb example where,use of classes will really make sense:?

i think it shoulb be like this

$i = new introduceYourself("someone");$intro = $i->writeName(); 

there are several advantages in oop,
you can use functions with similar names in different classes,
also you dont need to define varibles every time to the functions in classes.
eg. if private $_name; is set, you can request its value in every function simply by using $this->_name;

Thanks,2 advantages making sense

Im writting a varry basic understanding of oop

class Car{
var $wheels = 4;
var $doors = 4;

function wheelsdoors()
{
return $this->wheels + $this->doors;
}

}

$car=new car();

echo $car->wheels."<br/>";
echo $car->doors."<br/>";
echo $car->wheelsdoors() ."<br/>";

OOP has serveral advantage over POP. To mention few
1. The system you are developing reflects real world model and so it will be quite easy to implement (However pain in 4$$ if you dont understand OOP concepts and cant visualize the system)
2. This code is modular and so modification and maintaining code becomes easy.
3. You can re use the code, to achieve maximum re usability and so it reduce redundant code and so less efforts required.

Some more i can say is security, abstraction, and lot more.

All this I mentioned is just little part of advantage of whole OOP paradigm, advantages are much more.

Added after 10 minutes:

The concept you have currently in your mind is not pecfectly true. In OOP, we map real world entities (objects) into class. Class will also reflect the attributes that real world object has and what operation it can do (functions).
If we take a simple example of Car (as Ponick used), to make it follow good style of OOP, we may make following classs,

class Car {
private $name, $model, $manufacturer, $class, $year;
public function start()
{
}
public function accelerate() 
{
}
public function brake()
{
}
public function stop()
{
}
} 

Thus it will reflect real operations and attributes. It will have accessor method( get methods ) & mutator methods (set methods).
I hope, this example gave you an basic idea about OOP paradigm
