apc_clear_cache not working from command line in php

Question

I have a php script which clears apc. The script is working fine, when I opening it using browser, but when I am running that file from command line, it is not clearing cache.

I checked for apc.enable_cli setting, and that is also on (check the screenshot).

And here is my php-code

<?php

if (isset($argv[1])) {
    $key = $argv[1];

    $info = apc_cache_info("user");
    foreach ($info['cache_list'] as $obj) {
        if (strstr($obj['info'], $key)) {
            apc_delete($obj['info']);
        }
    }

} else {
    apc_clear_cache("user");
}
?>

What am I missing or doing wrong?

I think you should also post the code which clears the cache — Jakub Jankowski, Oct 14 '16 at 10:50
I'm not very familiar with PHP, but maybe it has something to do with permissions? Is there any error displayed when you run the file from command line? — Jakub Jankowski, Oct 14 '16 at 11:21

You can't clear APC cache from command-line, as you're not hitting the same APC segment of your webserver.

Note that enable_cli only allows you to use APC in a CLI environment, but creates a segment for your script, and destroy it at the end of the script. It doesn't use the same segment because it doesn't know about your webserver.

You have two options:

call your script through FastCGI (see below)
call the webpage with file_get_contents() or the like, using http://

If you need to access APC data, you can also read my article: https://www.dugwood.com/949904-php5-opcode-caching-and-memory-storage-with-apc-xcache-in-command-line-interface-cli-or-cron.html

I did use : curl -s 127.0.0.1/clear_cache.php > /dev/null & and wrote the code in php file — kadamb, Apr 20 '17 at 09:19
