Chapter 9. Working with Strings, Dates, and Times

No matter how rich Web content becomes, HTML lies behind it all, pushing string-based content out to Web browsers. It is no accident, then, that PHP provides many functions with which you can format and manipulate strings. Similarly, dates and times are so much a part of everyday life that it becomes easy to work with them without thinking. However, because the quirks of the Gregorian calendar can be difficult to work with, PHP provides powerful tools that make date manipulation an easy task.
