Other String, Date, and Time Functions

PHP does not lack for functions, especially for common items such as strings and dates. It is worth your while to bookmark the following chapters in the PHP Manual:

• Strings at http://www.php.net/manual/en/ref.strings.php

• Date/Time at http://www.php.net/manual/en/ref.datetime.php

  In addition to keeping up with functions as they are added to PHP, the user-contributed notes for each function often offer solutions to various programming tasks that you might find useful as you build your own applications.
