    [total_miss_count] => 201
    [file_entries] => Array
        (
            [1] => Array
                (
                    [file_name] => c:\inetpub\wwwroot\checkcache.php

                    [use_time] => 7
                    [last_check] => 10
                    [hit_count] => 454
                    [function_count] => 0
                    [class_count] => 1
                )
            [2] => Array (...iterates for each cached file)
        )
