When debugging the server environment, if the website code is updated, it cannot take effect immediately. Opcache needs to wait for the cache update to take effect, which is inconvenient for debugging.

php.ini default configuration

opcache.validate_timestamps=1

opcache. validate_freq=3 //By default, changed files are verified every 3 seconds and the cache is updated

Solution:

1 Development environment:

Will be revised to read:

opcache.revalidate_freq=1 //You can change 3s to 1s. The changed files will be verified every 1s and the cache will be updated

opcache.validate_timestamps=0 //The online environment is not enabled by default. If it is not enabled, cache will always be used

<?php

opcache_reset();
