How do I clean up the previously cached opcode when the online PHP code is updated?

opcache.validate_timestampsDefault isOFF

• Opcache sets the number of seconds per opcache.revalidate_freq to check if the script is updated. If you disable this option, you must manually reset the Opcache using the Opcache_reset () or opcache_invalidate () function, or you can make the file system changes take effect by restarting the WEB server.

opcache.revalidate_freqUnits 秒 Default to2

• Checks whether the script timestamp has an updated period, in seconds. Setting to 0 causes Opcache to check for script updates for each request.

From official documents:
will be opcache.validate_timestamps set toTrue
will be opcache.revalidate_freq set to an appropriate value, as 30 this time is flexibly adjusted to the server pressure.

Once set, the worst-case code update takes effect 30 seconds later and takes effect as soon as you can.

OpCode has cache time, waiting for it to expire.
