The code is set up to allow for alternative years and months which can be passed in with the _GET super-global but for now you are going to concentrate only on the current month. As you progress with the examples in this chapter you will see how you can use Ajax to really improve the functionality of this module and create some very cool applications. The code itself is fairly simple to decipher. It simply uses the date function in PHP to determine the beginning and end dates and then build the calendar accordingly. This is a prime example of using PHP s server-side scripting in conjunction with Ajax to create a nice little application as shown in Figure 3-1 . Next you ll work on progressing your application. s My Calendar Before My Calendar November 2005 Su M Tu w Th F Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 After Figure 3-1.

Basically I have built a way to feed a list of objects CHAPTER 3 PHP AND AJAX 33 through an array a database solution would be more effective but that is outside of the scope of this example and will be shown later in the book and then display them based on what the user has entered. The user can then click the name to fill out the field hence .
