PHP PHP 5.6.0 Released

remember to temporarily comment out memcached backends in your PHP apps like Xenforo BEFORE upgrade of PHP 5.6.0

hehe.. I am mindful of this, as I actually forgot to do that myself

Now bring on PHP NG alpha testing PHP-FPM - PHP 5.7 (PHPNG) support testing for Centmin Mod betas | Centmin Mod Community

 

@Andy when you ran centmin.sh menu option 5 and specific PHP 5.6.0 as the version to upgrade to, did you answer yes when prompted for Zend OpCache install ? As answering yes, will remove APC Cache as the php opcacher and use Zend OpCache. The same if you ran menu option 12 and submenu option 1 to install Zend Opcache - it will replace APC Cache as PHP opcacher.

You would of seen some prompts like below

Code:

Do you want to run YUM install checks ?  [y/n]

This will increase your upgrade duration time wise.
Check the change log centminmod.com/changelog.html
to see if any Nginx or PHP related new additions
which require checking YUM prequisites are met.
If no new additions made, you can skip the
YUM install check to speed up upgrade time.

[y/n]:
PHP Upgrade - Would you like to continue? [y/n] y

Install which version of PHP? (version i.e. 5.4.32): 5.6.0
Do you want to update to latest php-fpm.conf ? It will overwrite your existing php-fpm.conf [y/n]: n

-----------------------------------------------------------------------------------------
Detected PHP 5.6 branch.
You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if you web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

-----------------------------------------------------------------------------------------
Do you want to use Zend OPcache [y/n] ? y

Zend Opcache doesn't support user data caching like APC Cache, so switch to Memcached for Xenforo backend caching. I use Centmin Mod default installed Memcached server + memcached PHP extension via Libmemcached for this forum (Xenforo) instead.

PHP:

$config['cache']['backend'] = 'Libmemcached';

$config['cache']['backendOptions'] = array(
'servers' => array(
array(
'host' => '127.0.0.1',
'port' => 11211,
'persistent' => 'true',
'weight' => 1
)
)
);

 

Well Zend Opcache can be up to 60% faster than APC Cache for PHP opcode caching just no data caching support.

I did try APCu which is a fork for APC Cache to strip opcode caching and only do APC data caching but seems Xenforo doesn't support APCu see PHP-FPM - Experimenting with APCu data only caching with PHP 5.5/Zend OpCache | Centmin Mod Community

So your choice is install APC Cache again via centmin.sh menu option 9 (which will remove Zend Opcache automatically) or keep Zend Opcache + enable memcached server backend for Xenforo config.php.

you should have a XXX_opcache.php or XXX_op.php file in /usr/local/nginx/html (access as yourhostname/XXX_opcache.php). You can rename the file to whateveryouwant.php

then password protect the file and/or ip restrict it via nginx name vhost for virtual.conf https://community.centminmod.com/threads/how-to-properly-password-protect-a-directory-or-file.579

command shortcut typed in SSH window = vhostconf - only edits /usr/local/nginx/conf/conf.d/virtual.conf for your main hostname Nginx vhost as outlined in Getting Started with Centmin Mod

unfortunately you won't see production PHP NG until PHP 7.x

but you can alpha/beta test it as Centmin Mod supports PHP NG PHP-FPM - PHP 5.7 (PHPNG) support testing for Centmin Mod betas | Centmin Mod Community

 

there will be no PHP 5.7, next PHP version after PHP 5.6 is PHP 7.x (which will be PHP NG) strangely !

PHP: rfchp6

 

yeah only small improvement over PHP 5.5

Yeah same here, besides Digitalpoint proxy image addon not working with PHP 5.6.0
