When developing more complex PHP sites, especially forums, discussion boards and blogs where date and time functions are important, you’ll regularly encounter situations where you need to display and manipulate values based around the current date and time. PHP includes a range of functions which can help you to easily format and adjust your date and time displays to suit your needs. In this tutorial, we’ll look at some easy ways to display calendar information for your visitors.

One of the more surprising things you can learn about PHP is that it’s actually very useful when it comes to manipulating images of varying filetypes and formats. And a good thing too, since a lot of the internet is made up of pictures! The functionality of PHP in terms of image manipulation ranges from very simple resizing of images through to more complex effects and functions using image libraries such as ImageMagick

When developing a PHP project, whether it’s a simple website or a much larger web application, it’s always a good idea to take into account the potential appearance of errors in your PHP code. An error occurs whenever PHP tries to execute an instruction which either results in an impossible outcome, or otherwise prevents the script from executing in the manner intended by the programmer.

In this tutorial I'll introduce you to the concept of Classes and Objects in PHP. To put it simply, an Object in the context of programming languages is a data structure which can contain any number of variables and functions all held together under a Class name. This Class can then be created in the normal scope of the code and stored inside a new variable, and multiple copies of this same class can be created. This allows for an even greater level of code encapsulation, allowing more complexity to be accessed from simple commands.
