file_entries - an array that contains the information about all the cached files:
- file_name - absolute file name of the cached file
- add_time - time in seconds since the file has been added to the file cache
- use_time - time in seconds since the file has been accessed in the file cache
- last_check - time in seconds since the file has been checked for modifications
- hit_count - number of times the file has been served from the cache
- file_size - size of the cached file in bytes

范例

Example #1 A wincache_fcache_fileinfo() example


<pre>
<?php
print_r(wincache_fcache_fileinfo());
?>
</pre>

以上例程会输出：

    [total_hit_count] => 0
    [total_miss_count] => 1
    [file_entries] => Array

            [2] => Array (...iterates for each cached file)
        )
)
