Previous Comments: ------------------------------------------------------------------------ [2005-09-21 21:55:45] pjf at asn dot pl I made mistake in the code - here is the corrected version: touch("foobar"); echo file_exists("foobar") . "\n"; mkdir("foodir"); chdir("foodir"); echo file_exists("foobar") . "\n"; ------------------------------------------------------------------------ [2005-09-21 21:51:41] pjf at asn dot pl 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: --------------- [pjf@boogoo file_exists]$ ls file_exists.php [pjf@boogoo file_exists]$ cat file_exists.php <?php touch("foobar"); echo file_exists("foobar") . "\n"; mkdir("foodir"); echo file_exists("foobar") . "\n"; ?> Expected result: ---------------- [pjf@boogoo file_exists]$ php file_exists.php 1 Actual result: -------------- [pjf@boogoo file_exists]$ php file_exists.php 1 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34589&edit=1
