File Information is Cached by PHP

PHP Caches file metadata in status cache , causing wrong(cached) output from these file operation functions

stat(), lstat(), file_exists(), is_writable(), is_readable(), is_executable(), is_file(), is_dir(), is_link(), filectime(),fileatime(), filemtime(), fileinode(), filegroup(), fileowner(), filesize(), filetype(), and fileperms().

when i use filesize() function , I intend to get the correct size . I feel there is no valid reason behind caching this

WORKAROUND

call clearstatcache() before calling any of the above mentioned functions
