So, I thought I'd share something that might benefit those looking for a way to reset opcache in CLI.



As an example in my case, I'm running a Laravel app with a router script with the built-in web server for local development.  I enabled opcache with the following run configuration:



/path/to/php.exe -d zend_extension=php_opcache.dll -d opcache.enable_cli=1 -d opcache.memory_consumption=128 -d opcache.max_accelerated_files=10000 -d opcache.validate_timestamps=0 -d opcache.save_comments=0 -t project_path/public/ server.php



This is basically what artisan serve is doing behind the scenes, anyway, except without the opcache part.



I have some file watchers setup to detect changes and executes the following upon said change(s):



/path/to/php.exe -d zend_extension=php_opcache.dll -d opcache.enable_cli=1 -r "opcache_reset();"



The key is ensuring that you're enabling opcache in CLI.  I've been using this for some time, so I can attest to this being a viable solution without needing to create a script to execute somewhere in the document root, etc.



I'm only referring to Laravel as an example of why I chose to explore options for solving this problem.  This should translate to any scenario a developer would need to utilize opcache in their project(s) while using the built-in web server.

Run this to clear cache php -r 'opcache_reset();'

My workaround to clear cache via CLI is create a bash script like this:



#!/bin/bash

WEBDIR=/var/www/html/

RANDOM_NAME=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 13)

echo "<?php opcache_reset(); ?>" > ${WEBDIR}${RANDOM_NAME}.php

curl http://localhost/${RANDOM_NAME}.php

rm ${WEBDIR}${RANDOM_NAME}.php



put it in /usr/local/bin/opcache-clear and make it executable. 

When I want to clear cache I simply run "opcache-clear" inside terminal.

In some (most?) systems PHP's CLI has a separate opcode cache to the one used by the web server or PHP-FPM process, which means running opcache_reset() in the CLI won't reset the webserver/fpm opcode cache, and vice-versa.

It should be mentioned that opcache_reset() does not reset cache when executed via cli. 

So `php -r "var_dump(opcache_reset());"` outputs "true" but doesn't clean cache. Make file, access it via http - and cache is clean.

For people who have difficulties with constants and opcache_reset().

If you include a file with constant and do an opcache_reset() in the same file, you'll probably have some error like :



"Notice: Constant already defined"



The trick is to call opcache_reset() in an isolated file, then include another file that include the file with constants.



File a.php

<?php

opcache_reset();

include 'b.php'

?>



File b.php

<?php

include 'constants.php';

?>



File constants.php

<?php

define('MY_CONST', 'abcdef');

?>



With this trick, the opcache will be reset in a.php and when b.php will be included, the constants will not be in cache anymore.
