In the basics of object-oriented, let see how to define a class and create an object: When class is created, we can create any number of objects in that class. The object is created with the help of the new keyword.
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHPPreamble The hardest thing to learn (and teach btw,) in object oriented PHP ... is the basics. But once you get them under-your-belt, the rest will come much, much easier. But don't be discouraged! You just found the easiest to understand tutorial out there on OOP and PHP. It may sound like a boastful claim ... I know. But that's what the nerd zeitgeist is saying. ... Or so I've been told. Videos As an extra bonus, I've created a few video tutorials for you. They cover the same material as the written article and are designed to reinforce the article. •Introduction to Object Oriented PHP (4:05) •Why learn Object Oriented PHP (14:46) •Objects and Classes in PHP (5:26) •Build Objects in PHP - Part 1 (9:14) •Build Objects in PHP - Part 2 (9:41) •Build Objects in PHP - Part 3 (6:18) If you have questions/comments, you can contact me at: stefan@killersites.com !!!!© 1996 - 2013 www.killerphp.com
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHPLearn Object Oriented Programming (OOP) in PHP Object-Oriented Programming (OOP) is a type of programming added to php5 that makes building complex, modular and reusable web applications that much easier. With the release of php5, php programmers finally had the power to code with the 'big boys'. Like Java and C#, php finally has a complete OOP infrastructure. In this tutorial, you will be guided (step-by-step) through the process of building and working with objects using php's built-in OOP capabilities. At the same time you will learn: •The difference between building a php application the old fashioned (procedural) way, versus the OOP way. •What the basic OOP principles are, and how to use them in PHP. •When you would want to use OOP in your PHP scripts. People run into confusion when programming because of some lack of understanding of the basics. With this in mind, we are going to slowly go over key OOP principles while creating our own PHP objects. With this knowledge, you will be able to explore OOP further. For this tutorial, you should understand a few PHP basics: functions, variables, conditionals and loops. To make things easy, the tutorial is divided into 23 steps. !!!!!© 1996 - 2013 www.killerphp.com
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHPSTEP 1: First thing we need to do is create two PHP pages: •index.php •class_lib.php OOP is all about creating modular code, so our object oriented PHP code will be contained in dedicated files that we will then insert into our normal PHP page using php 'includes'. In this case all our OO PHP code will be in the PHP file: •class_lib.php OOP revolves around a construct called a 'class'. Classes are the cookie-cutters / templates that are used to define objects. !STEP 2: Create a PHP class Instead of having a bunch of functions, variables and code floating around willy-nilly, to design your php scripts or code libraries the OOP way, you'll need to define/create your own classes. You define your own class by starting with the keyword 'class' followed by the name you want to give your new class. 1.
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHPSTEP 3: Add data to your class Classes are the blueprints for php objects - more on that later. One of the big differences between functions and classes is that a class contains both data (variables) and functions that form a package called an: 'object'. When you create a variable inside a class, it is called a 'property'. 1.name = $new_name;!!! 7.!}!!8.!!9.!function get_name() {!10.!!return $this->name;!!© 1996 - 2013 www.killerphp.com
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHP11.!}!12.}!Note: Don't forget that in a class, variables are called 'properties'. !STEP 5: Getter and setter functions We've created two interesting functions/methods: get_name() and set_name(). These methods follow a common OOP convention that you see in many languages (including Java and Ruby) - where you create methods to 'set' and 'get' properties in a class. Another convention (a naming convention,) is that getter and setter names should match the property names. 1.name = $new_name;!!! 7.!}!!8.!!9.!function get_name() {!10.!!return $this->name;!!11.!}!12.}!Note: Notice that the getter and setter names, match the associated property name. © 1996 - 2013 www.killerphp.com
LEARN OBJECT ORIENTED PROGRAMMING (OOP) IN PHPThis way, when other PHP programmers want to use your objects, they will know that if you have a method/function called 'set_name()', there will be a property/variable called 'name'. !STEP 6: The '$this' variable You probably noticed this line of code: $this->name = $new_name The $this is a built-in variable (built into all objects) which points to the current object. Or in other words, $this is a special self-referencing variable. You use $this to access properties and to call other methods of the current class. 1.function get_name() {!2.!return $this->name;!!3.}!Note: This may be a bit confusing for some of you ... that's because you are seeing for the first time, one of those built in OO capabilities (built into PHP5 itself) that automatically does stuff for us. For now, just think of $this as a special OO PHP keyword. When PHP comes across $this, the PHP engine knows what to do. ... Hopefully soon, you will too! !STEP 7: Include your class in your main PHP page You would never create your PHP classes directly inside your main php pages - that would help defeat the purposes of object oriented PHP in the first place! Instead, it is always best practice to create separate php pages that only contain your classes. Then you would access your php objects/classes by including them in your main php pages with either a php 'include' or 'require'. !© 1996 - 2013 www.killerphp.com
