    To prevent losing all of your APC custom user data on an apache restart, use this function along with apc_bin_loadfile to save your APC Memory Data on a restart of apache.

    e.g.  Write a php script to dump the file and one to re-load the file.   Call the dump script directly before stopping apache, and then call the reload script directly after starting apache.

    <?php
    //saveapc
              apc_bin_dumpfile(array(),null,"/path/to/my/file.data");
    ?>

    <?php
    //loadapc
             apc_bin_loadfile("/path/to/my/file.data");
    ?>

    #  wget http://www.example.com/saveapc.php
    # /etc/init.d/httpd restart
    #  wget http://www.example.com/loadapc.php

    Particularly useful if you have a custom session handler using APC for storage

    Even more handy, update the httpd restart bash script to automatically make these calls for you on a restart
