Flushing the PHP file cache

    I have the PHP 7.1 file-based Opcode cache enabled in addition to the In-Memory OpCache:
    opcache.file_cache=/usr/home/altopl/public_html/.opcache

    As far as I can tell, when I click on “Flush PHP OPcache,” it only flushes/purges the In-Memory cache. I have to manually remove the file-based OPcache–which then gets automatically recreated the next time when I access my site.

    Would it be possible to add the file cache flushing to the “Flush PHP OPcache” functionality in some future release?

    Thanks much,
    George Wilder

    Hi George,

    This is a really nice idea, I’ll work on this feature during next weekend.
    Could you post me your opcache configuration please ?

    Hi mnttech,

    Thanks for the response.

    I am on a pair Networks shared host, which has ssh access. I am running PHP 7.1. This is my OpCache configuration:

    1738c1738,1739
    < ;opcache.enable=0
    —
    > zend_extension=opcache.so
    > opcache.enable=1
    1769c1770
    < ;opcache.revalidate_freq=2
    —
    > opcache.revalidate_freq=60
    1840c1841
    < ;opcache.file_cache=
    —
    > opcache.file_cache=/usr/home/altopl/public_html/.opcache

    To “flush” my file cache, I do:

    ==> rm -rf ~/public_html/.opcache/*

    Then I click on the “Flush PHP OPcache” button that was installed by your plugin.

    The file cache is automatically recreated the next time a PHP script is executed.

    Thanks,
    George

    I just released 2.4 version with support for opcache.file_cache.
    Let me know if it works correctly on your php version. I only tried on 7.0.28-1.

    Hello,

    I just updated to the latest version of the plugin, but I can’t empty the cache any more.
    I receive this error: PHP Fatal error: Uncaught UnexpectedValueException: RecursiveDirectoryIterator::__construct(/tmp/opcache): failed to open dir: No such file or directory in /var/www/[…]/wp-content/plugins/flush-opcache/flush-opcache.php:288

    I beleive this is because I don’t use file cache, and the new version of the plugin does not handle this situation. I tried to create the folder /tmp/opcache (with correct permissions), but the error persists.

    It would be nice to fix this bug, because it pretty much renders useless this plugin for those who have only memory cache.

    Thanks!
