How to Disable PHP OPcache

Introduction

PHP OPcache improves performance by caching PHP code. This is enabled by default, but in some cases may not be desirable, for example in a development environment or if you make changes to PHP files frequently. This can be disabled if needed.

How to Disable (PHP-CLI)

PHP settings are stored in /mnt/jrc-confs/php/conf.d/30-jrc.ini. Edit this file, for example with nano:

nano /mnt/jrc-confs/php/conf.d/30-jrc.ini

Locate the following line:

opcache.enable=1

Change its value to 0:

opcache.enable=0

Restart PHP-FPM in the AutoPilot interface in the Actions tab of your deployment.

After restarting PHP-FPM, OPcache is now disabled.
