The core of PHP6 is the built-in support for Unicode

PHP6 is an important upgrade in the PHP language. The core of PHP6 is built-in support for Unicode, which allows you to seamlessly use multiple languages in your application. Programmers in non-English-speaking countries can even name functions and classes in their own language. Unicode support immediately becomes extremely important, as more and more applications will be targeted to users around the world.

In addition to multilanguage support, PHP6 has added advanced OOP concepts, such as namespaces and deferred static bindings. If used properly, these features will allow you to better organize classes and methods.

PHP6 also offers the opportunity to break some of the back-compatibility and eliminate some of the existing functions. You will find that functions such as register_globals, MAGIC_QUOTES_GPC, and Safe_mode are removed, and the Ze1 compatibility mode of PHP4 is removed. In order to make the APIs more consistent, the order of the parameters of some functions is also updated.

Finally, PHP 6 contains new classes such as XmlWriter that add new functionality to the PHP language.

It is difficult to predict how language will evolve for any open source project. This chapter is largely based on fixed information and recommended modifications that may change before the final release of PHP6.
