After the online php code is updated, how does one clear the previously cached opcode?

Opcache. validate_timestampsThe default value isOFF

• OPcache checks whether the script is updated every second specified by opcache. revalidate_freq. If this option is disabled, you must use the opcache_reset () or opcache_invalidate () function to manually reset OPcache. You can also restart the Web server to make the file system change take effect.

Opcache. revalidate_freqUnitSecondsDefault Value:2

• Check whether the script timestamp has an update cycle, in seconds. If it is set to 0, OPcache checks the script update for each request.

From the official documentation:
SetOpcache. validate_timestampsSetTrue
SetOpcache. revalidate_freqSet to an appropriate value, as shown in figure30This time can be adjusted flexibly according to the server pressure.

After the above settings, the worst case code will take effect after 30 seconds, and will take effect immediately.

The opcode has a cache time. Wait until it expires.
