installation - Is APC compatible with PHP 5.4 or PHP 5.5? -

-

it doesn't seem apc has been updated coincide php 5.4 release (i wish have included apc in php core planned).

i can't seem find definitive answer whether current apc works php 5.4+. managed find ubuntu packages php 5.4, php-apc packages won't install.

zend opcache included in php 5.5

on 21st march 2013, php 5.5 beta 1 released including "zend opcache" - looks firmly replacement apc going forward included in php core, , have be maintained each new release.

i advise depend on apc it's opcode caching test code upcoming built-in opcode cache, , feed issues encountered ensure stable final release.

i not know means future of apc.

apc php 5.4+ still flagged beta

this means developers not consider stable. while many people experiencing no problems @ current svn releases, there still odd report of edge cases people under configurations, or under heavy load.

as want use in production environment, make sure thoroughly test release (beta or stable) in development or pre-production environments first. includes load testing!

as of 3.1.13 release, commits svn repository have slowed down , bug list doesn't have many recent additions. make of will.

anyone c / gdb skills , free time urged gloss on bug list , see if can fix anything, or improve free open source product rely on.

alternative solutions exist, wikipedia provides list of php accelerators.

on 13th of february 2013, zeev suraski announced availability of zend optimizer+ source code.

there has been quite lengthy discussion integrating zend optimizer+ php core in next major version (the version after 5.5). people may wish familiarise zend optimizer+ in advance, should case.
