apc

Let's assume I have these variables saved in apc, memcached and eaccelerator: article_1_0 article_1_1 article_3_2 article_3_3 article_2_4 How can I delete all cached variables that starts with article_3_ (they can reach up to 10000) ? is there any way to list the cached variables ? Arnaud Le Blanc The slow solution For APC: $iterator = new APCIterator('user', '#^article_3_#', APC_ITER_KEY); foreach($iterator as $entry_name) { apc_delete($entry_name); } For eaccelerator: foreach(eaccelerator_list_keys() as $name => $infos) { if (preg_match('#^article_3_#', $name)) { eaccelerator_rm($name); } }

I have issue with PHP7 and APCu. After installation I got this error: Fatal error: Call to undefined function Doctrine\Common\Cache\apc_fetch() APCu is 100% enabled, I see it in the phpinfo(); And when I try apcu_fetch() it works. How to use APCu in Symfony 2.8? Tobske This answer is obsolet. The correct answer is the one from François Breton. In PHP 7 you have to add an additional module to your PHP setup: apc.so This is a module that enables backward compability to apc for apcu. This is kind of confusing... See http://php.net/manual/de/apcu.installation.php for more info. If you are using

Imagine you have the following array of integers: array(1, 2, 1, 0, 0, 1, 2, 4, 3, 2, [...] ); The integers go on up to one million entries; only instead of being hardcoded they've been pre-generated and stored in a JSON formatted file (of approximately 2MB in size). The order of these integers matters, I can't randomly generate it every time because it should be consistent and always have the same values at the same indexes. If this file is read back in PHP afterwards (e.g. using file_get_contents + json_decode ) it takes from 700 to 900ms just to get the array back — "Okay" I thought, "it's

APC is showing 100% fragmentation. Is this bad? Does it mean that it's not helping at all? What paths do I go down to improve situation? Thanks in advance. In my experience, yes. I had a system where APC was showing 100% fragmentation, and performance was bad. I increased APC's memory limit (to 200 MB in my case -- but we had a lot of code) enough to give it some slack room. Fragmentation dropped to zero, and IIRC, CPU usage on the server dropped by 50%. Also, make sure you're using the apc.php script that comes with APC to monitor fragmentation/utilization. We've even written a nagios check

Currently on a very large project that I do not plan to re-use for another site, I have the site's name hardcoded into the files everywhere. Now, if I were ever to change the site name it would take a lot of effort to change that everywhere. I know the obvious solution is to just store the name as a variable or a constant, but I guess you could call it my micro-optimizing way of thinking: I always figured it would be one less thing PHP has to parse. I do realize it won't make much difference, but I just wanted to know whether using an opcode cache like APC would mean that PHP wouldn't even

I wrote my own little PHP MVC Framework, and now Im exploring caching strategies in PHP MVC Frameworks. Im thinking about what can be cached, where and how. The framework I have is simple MVC Framework. I have front controller, that boots up application, registers class auto loading, sets up php run time directives... and at the end analyses URL and dispatches request to appropriate controller, method, action controller, how ever you want to call it. From controller, I have access to Domain Objects, and Data Mappers that can persist Domain Objects to some storage, most of the time Relation

What is the best PHP handler for this situation in term of performance first, and security later? Is it suphp / dso / fcgi / cgi ?
