Pro PHP 5 will take you to the next level of application development by introducing sound development principles. (These updated principles have been made possible due to various enhancements.) The book pairs these enhancements with a growing number of third-party projects, such as Phing, PHPUnit, and PHPDocumentor, all of which will improve your application development activities. Coverage also includes the utilities XDebug2, APD, and KCache Grind.

Author Marcus Whitney presents a wide array of intermediate- and advanced-level topics that include application testing, tuning, using installation and packaging procedures, writing language extensions, and more. In addition, he’ll show you how to extend PHP by writing C-based extensions.
