PHP 7 is finally Released After Years of Development
Web developers around the world have waited for this day for quite some years, but now that PHP 7 is officially out, work must begin on migrating their code to this newer version.
Unlike previous releases like PHP 5.3.x and PHP 5.5.x, where the PHP team introduced a slew of breaking changes, PHP 7 comes with minimal syntax modifications, this new release focusing more on improving performance and upgrading PHP’s core interpreter.
Nevertheless, if there are developers that were still using some of PHP’s older extensions and SAPIs, they’ll have a little bit of work, having to remove any legacy code from applications. Situations like these are bound to be rare, since the PHP team already deprecated most of these older tools in previous releases, and is now only removing the actual code from PHP’s core. A full list is available here.
As mentioned above, PHP 7 is focused on speed, and benchmarks carried out over thepast few months, have shown it to be almost twice as fast as older PHP 5.x releases, and neck and neck with Facebook’s HHVM project, a Just-In-Time compiler for PHP code.
Since many PHP open source projects have known about the impending PHP 7 release since last winter, most have already updated their code to support PHP 7, and the ones that didn’t will surely do after today’s official release.
For interested developers, a full list of new features is available on PHP’s official manual.
