Summary
Even though PHP5 is a feature-rich language, you might want additional functionality. Therefore, this chapter introduced you to PEAR, the PHP Extension and Application Repository, a distribution system via which you browse and download additional functionality. The system is extremely easy to use and typically comes ready to go with your PHP installation. Using this and some of the classes obtained through it, you can solve some of the problems you might have in PHP, including limitations with dates and times.
The next chapter covers some best practices when working in a group environment (practices that you can also use when working by yourself). Some simple procedures and policies will help keep your application stable, maintainable, and fun to continue working on.
