PHP 5.3 allows us to group the classes, the constants and the functions we define into separated groups, also known as namespaces. Doing so we can cope with possible names collisions.
Unlike previous PHP versions that introduced new features their syntax derive from Java (e.g. the extends and implements keywords), this time the developers of the PHP programming language chose to follow the syntax of C#.
The following video clips overview simple code samples that use this new features. The source code is available in my ‘PHP Fundamentals’ course. The community version of this course is available for free personal usage at www.abelski.com.
