Whether you’ve used OOP before in PHP or not, this chapter will show you what it is, how it’ s used, and why you might want to use objects rather than plain functions and variables. We’ll cover everything from the “this is how you make an object” basics through to interfaces, exceptions, and magic methods. The object oriented approach is more conceptual than technical—although there are some long words used that we’ll define and demystify as we go!...

You need to implement these steps every time you want to upload files, so it makes sense to build a script that can be reused easily. That s why I have chosen to use a custom class....

  • GENERATING THUMBNAIL IMAGES It doesn t matter which order your methods appear inside the class definition, but it s common practice to keep all public methods together after the constructor and to put protected methods at the bottom of the file. This makes the code easier to maintain. Insert the following definition between the constructor and the checkType() definition: public function test() { echo 'File: ' . $this-_original . '
    '; echo 'Original width: ' . $this-_originalwidth . '
    '; echo 'Original height: ' . $this-_originalheight . '
    '; echo 'Image type: ' .
