Object-Oriented Programming with PHP
Video Duration: 0s 1h 57m Intermediate Updated Apr 10, 2013


View Course Description

Whether you're enhancing or optimizing existing code or just starting from scratch, there's never a better time to start integrating object-oriented design techniques. This course shows how to integrate the principles of object-oriented programming into the build of a PHP-driven web page or application. After an overview of what objects and classes are and why they should be used, author Jon Peck dives into creating and instantiating objects, then defining the class relationships and interactions that will form the basis of your coding arsenal. The course also shows how to leverage PHP objects and implement design patterns, and looks at steps you can take to continue adding to your programming tool belt.

Topics include:
  • Historical overview of object-oriented PHP
  • Defining classes
  • Creating a method/object context with $this
  • Accessing classes without instantiation
  • Creating a database class
  • Extending and abstracting classes
  • Cloning and comparing objects
  • Error handling with exceptions
  • Implementing design patterns, such as the factory and strategy patterns


(music playing) In this course, we'll look at the fundamentals of object-oriented programming with practical PHP examples. I'll start by showing you how PHP implements classes and properties by creating an object. Then, show you how PHP's magic methods and class relationships work. We'll build a system for storing street addresses that uses design patterns. We'll be covering all these topics, plus plenty of other tools and techniques used in PHP applications all around the web.

Q: I'm not seeing warnings or errors in my environment like the video; why not?
A: Your PHP configuration is probably configured not to show them to you. This is often true on commercial web hosts and is often the default. Fortunately, there are multiple ways of resolving this.

The easiest way would be to explicitly enable error reporting at the top of the PHP script you wish to debug.

error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);

Alternatively, if you have access to your php.ini file and you want to always have error reporting on, change error_reporting = to a development friendly value of

error_reporting = E_ALL | E_STRICT

then change display_errors = to

display_errors = On

Finally, if access to the php.ini file is not available, you can add the following directives to your .htaccess or VirtualHost configuration for Apache:

php_value error_reporting 32767
php_value display_errors 1

Q: This course was updated on 4/10/2013. What changed?

A: The author rerecorded some of the tutorials to add more background information and better graphics.
