PHP 7.0.2 Official Release _php instance

For more than seven years, PHP has been the fourth most popular programming language to drive more than 200 million websites worldwide, with more than 81.7% of the world's public websites using PHP on the server side. PHP has had its biggest leap since 2004 this week, as PHP 7 has been released. PHP 7 's biggest feature is dramatically improved performance, which in some WordPress benchmarks can be up to 3 times times the performance of PHP 5.6.

PHP 7 also has some minor improvements, such as the ability to significantly reduce memory usage, add return type declarations, and more. PHP 7 contains some major security improvements, such as removing PHP safe mode, adding magic quotes, some new reserved keywords, and more. This means that Web applications like WordPress need to be partially redesigned to prepare for PHP 7 release, and now WordPress looks completely compatible with PHP 7.

Although PHP 7 has been released, it will take years for the Web application, especially for enterprise Web applications, to take several years to upgrade to the new version of the platform. However, many web developers agree that PHP 7 's huge performance improvements are appealing to them.

PHP 7.0.2 Release: wordpress speed 3 times times!

When it comes to PHP, someone would say it's the best programming language in the world. In popularity, more than 81.7% of the world's servers are now using the PHP language, which drives more than 200 million websites worldwide. The release of the PHP7 official version early last month ushered in the largest version update since 2004. Now, PHP 7.0.2 is officially released.

The most significant change in PHP7 is the dramatic improvement in performance, which is close to the PHP execution engine HHVM developed by Facebook. In the WordPress benchmark performance test, the speed is more than 5.6 times faster than the version, greatly reducing 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. In terms of security, remove the PHP security mode, add magic quotes, and so on. Not only that, the new version also supports 64-bit, and includes the latest version of the Zend engine.
Although officially released, the popularity of PHP7 will take a long time, many web hosting services, enterprise Web applications for compatibility reasons, may continue to use the old version for a long time in the future. However, at present, the world's most popular PHP blogging platform WordPress has been the best preparation for PHP7.
