PHP 7.0.2 Official Release _php instance

For more than seven years, PHP has been the fourth most popular programming language, driving more than 200 million sites worldwide, with more than 81.7% of the world's public Web sites using PHP on the server side. PHP has had the biggest leap since 2004, since PHP 7 has been released. The biggest feature of PHP 7 is that it greatly improves performance, and in some WordPress benchmark tests, performance can reach 3 times times that of PHP 5.6.

PHP 7 has other minor improvements, such as significantly reduced memory usage, adding return type declarations, and more. PHP 7 contains some significant security improvements, such as removing PHP security mode, adding magic quotes, some new reserved keywords, and so on. This means that Web applications like WordPress need to be partially redesigned to prepare for the release of PHP 7, and now WordPress appears to be fully compatible with PHP 7.

Although PHP 7 has been released, it will take years for the Web application, especially for enterprise Web applications, to be upgraded to a new version of the platform. However, many web developers believe that the huge performance improvements of PHP 7 are attractive to them.

PHP 7.0.2 Official release: WordPress speed upgrade 3 times times!

When it comes to PHP, someone would say it's the best programming language in the world. The popularity of the world, now more than 81.7% of the server back end of the use of PHP language, it drives more than 200 million sites around the world. The official version of the PHP7 was released early last month, ushering in the biggest update since 2004. Now, the PHP 7.0.2 is officially released.

The most notable change in PHP7 is the great performance boost, which is close to the PHP implementation engine HHVM developed by Facebook. In the WordPress benchmark performance test, the speed is 2~3 times faster than the 5.6 version, which greatly reduces the memory footprint. PHP7 also has some changes in language, such as adding a return type declaration, adding some new reserved keywords, and so on. On the security side, remove the PHP security mode, add magic quotes, and so on. Not only that, the new version also supports 64-bit, and contains the latest version of the Zend engine.
Although officially released, the popularity of PHP7 will take a long time, and many web hosting services, enterprise Web applications, for compatibility, may continue to use older versions for a long time to come. For now, however, WordPress, the world's most popular PHP blogging platform, has been best prepared for PHP7.
