PHP Bug Type: *Directory/Filesystem functions
Bug description: Strange effects of file_exists() etc. caching
Description:
------------
I find caching of file_exists() and similar functions
causing strange results - as presented by attached code,
it might cause unexistent files to... "exist" :).
Reproduce code:
---------------
[EMAIL PROTECTED] file_exists]$ ls
file_exists.php
[EMAIL PROTECTED] file_exists]$ cat file_exists.php
<?php
touch("foobar");
echo file_exists("foobar") . "\n";
mkdir("foodir");
echo file_exists("foobar") . "\n";
?>
Expected result:
----------------
[EMAIL PROTECTED] file_exists]$ php file_exists.php
1
Actual result:
--------------
[EMAIL PROTECTED] file_exists]$ php file_exists.php
1
