What is "php-5"

In June 2004 version 5 of PHP was released, introducing a new object orientation model, including redesign of constructors and addition of destructors, access visibility, object abstraction and object interfaces.

The PHP object handling has been completely rewritten, allowing for better performance and more advantages. While in the previous version it took a lot of effort to meet both object orientation and project patterns (some were not possible), PHP 5 came to remedy this deficiency. It still suffers in this sense, however, due to problems being a language of typing weak.
