How to enable PHP OPcode caching for Drupal 8?

Question

I want to enable PHP OPcode caching for Drupal 8 installation. I have the following in Xampp php.ini. However, I still get opcode not enabled. What am I doing wrong??

opcache.enable=1

engine = On
zend_extension=php_opcache.dll


opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

Solution 1

Here is nice post about OPCache: How to use PHP OPCache?

And here is for localhost with XAMPP: https://www.drupal.org/node/2623566

First of all check your PHP version. Before and after PHP 5.5 things are little bit different. You may refer for difference here http://php.net/manual/en/opcache.installation.php

Also if you are using zend extension then full path of dll is required in below

zend_extension=/your/path/tod/dll/php_opcache.dll

Also make sure to use correct one in terms of threaded or non threaded version.

Open php.ini file. There You have to uncomment this line of code: zend_extension=opcache.so . After that restart lampp/xampp. It works for me.

Use formatting tools to make your post more readable. Code block should look like code block. Use bold italics if needed
