Unfortunately, relatively little information is available about writing
efficient PHP applications -- hence the motivation for writing this
tutorial. The following are some resources that I used in writing
- Visit the
PHP Web site (http://www.php.net).
- If you have problems with a particular function,
read the user-contributed notes and comments throughout the PHP manual (http://www.php.net/manual/en/).
Chances are good that someone else has experienced the same problem and added notes about it to the manual.
- The article, Optimizing PHP Scripts suggests "programming time
is expensive." Read how to improve the performance of
your PHP applications from other angles. It also contains a couple of
useful sections on when to optimize, and how to measure performance of
pieces of your application.
- Check out Zend, the
commercial side of PHP. It provides additional products that can help improve
performance: Zend Cache and Zend Optimizer.
- See "Using Strings" on the Zend Web site for more
information on the different uses of strings in PHP.
- Get further information on Internet Explorer's handling of MIME-types from
Microsoft Support WebCast: MIME-Type Handling in Microsoft Internet
Explorer, January 11, 2001. In particular, refer to the Questions
& Answers section at the end of the Web cast where several
questions address the possible need for two GET requests.
- Learn how to make your wireless content more dynamic with the use of PHP in the IBM developerWorks tutorial,
Flex your PHP (developerWorks, March 2002).
Web site and get the useful PHP Quick Reference Card.
