Summary
This chapter covered a number of issues to be aware of when dealing with dates and times in PHP. We saw functions for obtaining dates and times and for formatting them for output to the client browser, and even some new database functions for making queries more powerful.
We also learned, however, that timestamps as implemented on many of the systems on which PHP operates provide limited value. Later in this book, you will find some better solutions to this problem.
The next chapter examines XML web services, a way that servers can expose functions and interesting new functionality (which we can then call using XML text and the HTTP protocol, without the need for complicated new constructs).
