APCu classes

[Jurigag]

In php7 in apcu there is no apc_* methods emulation. Phalcon has classes using only apc_*, not apcu. On some point if php 7 support in 2.1.x or later versions like 2.2.x or something will be better/stable we should add classes using APCu, so people don't need to install apcu_bc(which adds polyfill for apc_* methods on php7).

Even with apcu_bc I'm getting an error.

$cache->save(...);
// gives error: Call to undefined function apc_store() 

apcu 5.1.4
apcu_bc 1.0.3

You sure it's loaded ? Check phpinfo. And your files .ini files. apcu_bc is added as apc.ini, but it MUST be loaded AFTER apcu.ini I don't have a problem with apcu_bc.

That solved it, thank you. I was loading it in the wrong order.

+1 for APCu support

I'll be honest: I haven't fully done my research on this one. I did a bit of Googling for "PHP in-memory caches" and saw that my options were memcached and APCu, and reading up on the two it sounds like memcached is better for distributed environments or setups where more than PHP needs to read the cache, but if it's just PHP one a single server APCu is supposedly more performant. Based only on that minutia of knowledge I Google'd "Phalcon APCu support" and found this thread

I'll try installing APCu + APCu_bc and if it works as described then that will solve all of my issues for now (I have root access and can install whatever I need), but I know some people may not have the ability to install arbitrary extensions. Not to mention more extensions = more bloat, more memory usage, and longer load times.

Extensions are loaded only on startup, apcu_bc is like a few kb of memory usage, and it has almost none bloat beacause it's just calling apcu functions.

Fixed in the 3.2.x branch.
