Why PHP?

With so many programming books on the market these days—and so many PHP

books—you might wonder what another book could accomplish. PHP is a widely used

language and has experienced much growth in recent years in the enterprise market.

Web environments like Facebook, Flickr, portions of Yahoo!, and Wikipedia all use

PHP in a significant way, and web content management systems like Drupal, Joomla,

and WordPress are also powered by PHP. IBM is also showing a lot of interest in integrating

its technologies with PHP. For these reasons, it makes sense for the community

to assist beginning and intermediate programmers in becoming familiar with all the

best areas of this language.
