PHP 7.0 Final will ship November 12th 2015

Very exciting to see the PHP team set the date for the PHP 7.0 final (gold) release.

https://wiki.php.net/todo/php70#timetable

Thursday November 12th – 90 days from today, mark your calendars!

It will be as if millions of servers cried out as their loads were cut in half.

The first PHP 7.0 release candidate will ship August 20th, 2015 (this coming Thursday!)

All changes to PHP 7.0 now are stabilization/fixes only (feature frozen).

In 30 days, on September 14th 2015, the PHP team will start the PHP 7.1 master trunk branch as PHP 5.4 is marked “end of life”

If you need legacy code support, be sure to read my post on how to put mysql functions back into PHP 7.0


How to put MySQL functions back into PHP 7

PHP 7 will go “release candidate” on August 20th 2015 which is very exciting because it will instantly be twice as fast as PHP 5.6 (and all previous versions). PHP7 gives HHVM a run for the money and takes 5 minutes to compile instead of hours for HHVM.

But there is a catch – if you have any legacy code that uses the mysql_* functions, they will stop working entirely in PHP 7. Not just a warning, not just deprecated, but gone, fatal.

However, it is easy to get them back without using a wrapper or modifying your code…

phpinfo page for HHVM HipHop Virtual Machine

So you finally got HHVM 3.2 installed and running
and instinctively go to your phpinfo page to check it out…

but there nothing there, only “HipHop” …disappointing isn’t it?

So I whipped this up real quick as a phpinfo replacement:

HHVMinfo on github or direct download

Suhosin comes back from the dead, bringing security to newest PHP versions

수호신

While everyone has been distracted admiring PHP-NG, a great PHP project has quietly come back from the dead – Suhosin !

Suhosin is a well regarded security extension for PHP by Stefan Esser that had stopped getting updates after PHP 5.3. Perhaps it was due to more dramatic internal changes to the PHP core with 5.4 making it difficult to keep up. Linux distributions such as Debian that added Suhosin seeing its value, dropped it after updates stopped. Suhosin only worked up to PHP 5.3 – until now.

Suhosin can do neat tricks like disable EVAL and the regex /e modifier in PHP which the core of PHP cannot do by itself (or more accurately the core developers refuse to address). Suhosin also has many other options to help make PHP safer to use in a shared environment or where a server might be running a great deal of third-party code (ie. WordPress/plugins).

How to build HHVM 3.8 on CentOS 7

2015 UPDATE: new wiki page for HHVM on CentOS7 with alternate instructions
—-
While building HHVM (HipHop Virtual Machine) for faster PHP on CentOS 6.x was pretty much a nightmare because almost none of third-party libraries are available from major repositories, the freshly released CentOS 7.0 solves most of this problem as it has far newer packages available from EPEL (because it has roots in more modern Fedora 19).

Note that unlike PHP/PHPNG, HHVM requires major resources to build. You may be used to making PHP in 15 minutes on a little old 256mb 1ghz box. You can forget that with HHVM which is a beast to compile. 1gb ram minimum and lots of cpu power required to keep it an hour or two (this is part of why PHP NG instead is so exciting because it will be so much easier to custom build).

PHP NG within 10-25% of HHVM performance

Zeev Suraski (CTO of Zend and therefore an extremely qualified authority on PHP NG) has written a fascinating article comparing the performance of PHPNG against the current HHVM versions. A must read.

phpng-vs-hhvm

Perhaps even more importantly, he has written about the current state and future of PHP NG.

PHP NG now nearly TWICE as fast as PHP 5.6

correction: php core developers have urged that it is improper to call this version “5.7” (despite the versioning file stating so)

PHP 5.7 PHP NG is still in alpha development, however it is starting to show breathtaking performance improvements over 5.6 while maintaining virtually complete compatibility.

Dmitry Stogov has been hard at work since his first announcement in mid-January 2014 and milestone update in early-May to keep folding in more and more ideas to increase PHP speed (with significant contributions by Xinchen Hui, Nikita Popov and others).

Six months later in mid-July, their efforts are really bearing fruit and PHP 5.7 NG is about to become nearly 100% faster than PHP 5.6 when rendering the front page of a stock WordPress 3.6 installation:

PHP 5.6, 1000 renderings of WP front page = 26.756 seconds

PHP NG,  1000 renderings of WP front page = 14.810 seconds

and he is not even done yet, based on all his proposals and notes as you can follow on http://wiki.php.net/phpng
