On the core functions of PHP example analysis, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

PHP is one of the languages that we always pay close attention to. With the upgrade of PHP6, its function is becoming more and more powerful. Let's give a detailed introduction to the core content of PHP here. Andrei Zmievski, the core developer of PHP, proposed in a keynote speech at the recent 2009 Zend/PHP conference: "in the next major PHP6 upgrade, we will help developers write applications that can be deployed in many different language markets by supporting Unicode."

If you only develop applications for a special language market in commercial development, you will lose business opportunities elsewhere. As early as April 2006, Andrei Zmievski proposed the need to support Unicode in the future, and he thought it was long overdue. The so-called Unicode means that no matter what platform, what language, all use a unified coding, for PHP6, including the string type, will be built-in Unicode.

PHP6's Unicode makes it easier to write applications that can handle a variety of languages and codes, such as an application that supports both Chinese, Japanese and English, for users from China, Japan and English-speaking countries at the same time. PHP's increased internationalization is a long-awaited and gratifying thing, especially for software developers who are not born in the United States and the United Kingdom and business owners who use PHP sites to provide services, including the growing number of Chinese foreign trade enterprise sites. Some vendors that provide PHP content management systems also report that it is very difficult for the current PHP version to support internationalization, so the internationalization to be upgraded will be very helpful to them.

From PHP's official website, we can see that the Unicode Completion Stats of PHP is about 70% as of today, but the core developers of PHP still need to complete Unicode development in areas such as cookie access and PDO (PHP Database Objects). "when this is done, we will test PHP6 on some well-known applications and frameworks, such as Drupal," Zmievski said. "

Gutsman, the core developer of PHP, said: PHP is now more widely used, and the economic downturn has accelerated the use of open source and PHP, because in the recession, companies have to increase productivity and reduce costs, and PHP can do just that.

It is also an important part of Web development language and platform, the development of Java. Because the initial enterprise Java is not suitable for Web load, it has been gradually replaced by popular lightweight frameworks such as Spring, and some Java developers have also turned to dynamic languages such as PHP, so the support of internationalization will play a greater role in the growth of the PHP camp. But for the implementation carrier of the Internet, Web development language / platform, their vitality itself comes from the continuous evolution and development with the development of the Internet, whether PHP supports Unicode or Java becomes lighter.

It is worth noting that PHP6 will also improve the handling of numbers, including long numbers. In addition, traits, different from vertical inheritance of classes, a function that can reuse code horizontally is also under consideration, and developers will not need to deal with multiple inheritance to add functions.

Zend also announced last week the beta version of Zend's PHP IDE--Zend Studio 7.1, which provides support for remote servers and integrates support for tasks. Version 7.1 is scheduled to be officially available at the end of 2009.
