How to clear APC cache entries?

I don't believe any of these answers actually work for clearing the APC cache from the command line. As Frank Farmer commented above, the CLI runs in a process separate from Apache.

My solution for clearing from the command line was to write a script that copies an APC clearing script to the web directory and accesses it and then deletes it. The script is restricted to being accessed from the localhost.

1. apc_clear.php

   This is the file that the script copies to the web directory, accesses, and deletes.

   <?php
   if (in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', '::1')))
   {
     apc_clear_cache();
     apc_clear_cache('user');
     apc_clear_cache('opcode');
     echo json_encode(array('success' => true));
   }
   else
   {
     die('SUPER TOP SECRET');
   }
   

2. Cache clearing script

   This script copies apc_clear.php to the web directory, accesses it, then deletes it. This is based off of a Symfony task. In the Symfony version, calls are made to the Symfony form of copy and unlink, which handle errors. You may want to add checks that they succeed.

   copy($apcPaths['data'], $apcPaths['web']); //'data' is a non web accessable directory
   
   $url = 'http://localhost/apc_clear.php'; //use domain name as necessary
   $result = json_decode(file_get_contents($url));
   
   if (isset($result['success']) && $result['success'])
   {
     //handle success
   }
   else
   {
     //handle failure
   }
   
   unlink($apcPaths['web']);
