With the release of PHP 7.3 Alpha3 last week, it means that PHP 7.3 is about to enter the feature freeze phase, no new features will be added, and subsequent beta and RC versions will be mainly fixed until the official release is released on November 29.
From the current update instructions, PHP 7.3 is not a version that focuses on new features, including more bug fixes. PHP 7.3 removes support for BeOS, improves PHP GC, and implements the more flexible Heredoc and Nowdoc syntax.
PHP 7 was officially released in December 2015. After more than two years of development and iteration, usage has been rising, but it still lags behind the PHP 5 series. The latest statistics for W3Techs.com are as follows:
The latest version of the PHP 5 series is PHP 5.6 released in 2014 and is the most widely used version. However, after six months, PHP 5.6 will completely lose official support. At that time, it may bring a round of user surge to PHP 7.
Everyone knows that when PHP 7 was released, it claimed to be twice as fast as PHP 5.6. What about the performance of PHP 7.3? Phoronix conducted a benchmark test when PHP 7.3 Alpha1 was released. It turns out that in the popular PHPBench benchmark, PHP 7.3.0 Alpha 1 is about 7% faster than the current PHP 7.2 stable version and 22% faster than PHP 7.0:
PHP 7.3 also performed well when using Phoronix’s own test suite. Significant improvements in both rendering and data processing tests.
