XF 1.4 How to enable Xenforo Backend Cache as Zend Opcache

[maxicep]

I'm using Zend Opcache as php caching on my server side and i think Zend Opcache may use for variable caching too.

So what should be right config parameter in config.php for Xend Opcache ?

$config['cache']['backend'] => '?'

I know that we write $config['cache']['backend'] => 'xcache' while using the xcache as variable caching.

Or should i install memcache, xcache or apc for backend caching ? Thanks

Zend Opcache cannot be used as a variable/value cache.

Thank you for reply.

So whats your advice for variable caching ? We are a big board and have about ~7million posts and ~2.5million members. I was using xcache for a long time but i want to hear some advices about that if i m wrong.

APCu may work, though I've heard mixed things. Memcached is the normal go to.

I know this is an old thread, but a quick FYI, since PHP 7 the opcache can be used to store variables/values, and it's exponentially faster than all the other caches since it doesn't have to serialize the data.

Opcache is specifically about caching the parsed versions of scripts. You can see this from the relatively small API it exposes: http://php.net/manual/en/book.opcache.php Are you sure you're not referring to another extension?

Since 7.0 if you can use file_put_contents like this:

function cache_set($key, $val)
{
$val = var_export($val, true);
$val = str_replace('stdClass::__set_state', '(object)', $val);
// Write to temp file first to ensure atomicity
$tmp = "/tmp/$key." . uniqid('', true) . '.tmp';
file_put_contents($tmp, '<?php $val = ' . $val . ';', LOCK_EX);
rename($tmp, "/tmp/$key");
}

function cache_get($key)
{
@include "/tmp/$key";
return isset($val) ? $val : false;
}

Its blazing fast in 7+, works in prior versions but isn't fast.

What about that usage? And where?

That was just a basic example of how to store and retrieve data with it, not how to implement it in XF.
