This arcticle introduces Object Oriented Programming (OOP) in PHP. I will show
you how to code less and better by using
some OOP concepts and PHP tricks. Good luck!
Concepts of object oriented programming:
There're differences between authors, I can mention that a OOP language must have:
- Abstract data types and information hidding
- Inheritance
- Polymorphism
The encapsulation is done in php using classes:
<?php
class Something {
// In OOP classes are usually named starting with a cap letter.
var $x;
function setX($v) {
// Methods start in lowercase then use lowercase to seprate
// words in the method name example getValueOfArea()
$this->x=$v;
}
function getX() {
return $this->x;
}
}
?>
Of course you can use your own nomenclature, but having a standarized one is useful.
