PHP Internals folks--
We're doing some performance work in WinCache, and we're finding that some
frameworks are...uh...enthusiastically using file_exists(), is_file() and
is_dir() functions on files/directories that don't exist. Every. Single.
Pageload.
Does the PHP stat cache include negative cache entries? If not, why not?
Are there any existing extensions that implement a negative cache for
file_exists(), is_file(), et. al.?
Thank you!
