A namespace is a method that prevents your functions, classes, and methods from being read due to name conflicts between functions or classes, rather than Prefix naming conventions. Therefore, by using a namespace, you can name a class name that someone else may already use, without worrying about errors during running. The following provides an example of using a namespace in PHP. You do not need to update or change the source code, because any PHP code you write can run well without a namespace. Because the namespace feature seems to be ported to PhP 5.3 x, if it can be used, you can reference the namespace in your own program. Namespace example <? PHP
// I'm not sure why I wocould implement my own xmlwriter, but at least
// The name of this one won't collide with the one built in to PhP
Namespace nathanagood;
Class xmlwriter
{
// Implementation here...
} $ Writer = new nathanagood: xmlwriter ();?> The Web 2.0 feature depends on how you use PHP and your current script. The current language and syntax differences may or will not affect the following features to the greatest extent, this refers to the PHP applications that directly allow you to reference web 2.0 features. Soap is a network service "speaking" protocol and supports many other languages, such as Java and Microsoft. net, although there are other methods to drive and use network services, such as the representational state transfer rest, soap is still the most common in making different platforms operable. In addition, soap is used in PHP extensions and pear libraries. Soap is not supported by default in PHP, so you can enable this extension or ask your ISP to enable it. In addition, the pear package allows you to create soap clients and servers, such as soap packages. If you change the default settings, soap will be enabled in PHP 6. This extension will provide you with easy implementation of soap clients and soap services, allowing applications you write to provide use or network services. If SOAP extensions are set by default, it means you cannot set them in PHP. If the PHP applications you develop and they are published to an ISP Server, you may need to check your ISP to verify soap and enable upgrade for them. XML in PHP 5.1 xmlreader and xmlwriter have become part of the PHP core, which makes it easier for you to use XML in your PHP program. Like soap extensions, if you use soap or XML, this is good news, because Php 6 is more suitable for you than the already released PhP4. In addition to some new features, the PHP 6 engine will delete some features that are already available in previous versions. Most of these features, such as register_globals and safe_mode, are regarded as "broken" in current PHP ". Because they may expose some security risks. In the effort to clear PHP, these will be deleted or discarded from PhP in the next version. Opponents think that most ISPs or enterprises will keep their current scripts because upgrading to PhP6 will destroy the current scripts, But supporters think they are very happy to see the PHP team fix these vulnerabilities and provide a clean, A secure running tool. Functions to be deleted from PHP Include: magic_quotes
Register_globals
Register_long_arrays
Safe_mode
