Just to make this more obvious (and so search engines find this easier): If you do fileops of any kind outside of PHP (say via a system() call), you probably want to clear the stat cache before doing any further tests on the file/dir/whatever. For example: <?php // is_dir() forces a stat call, so the cache is populated if( is_dir($foo) ) { system("rm -rf " . escapeshellarg($foo)); if( is_dir($foo) ) { // ...will still be true, even if the rm succeeded, because it's just // reading from cache, not re-running the stat() } } ?> Pop a clearstatcache() after the system call and all is good (modulo a bit of a performance hit from having a cleared stat cache :-( ). ---- Server IP: 72.52.91.14 Probable Submitter: 64.235.144.239 ---- Manual Page -- http://php.net/manual/en/function.clearstatcache.php Edit -- https://master.php.net/note/edit/116554 Del: integrated -- https://master.php.net/note/delete/116554/integrated Del: useless -- https://master.php.net/note/delete/116554/useless Del: bad code -- https://master.php.net/note/delete/116554/bad+code Del: spam -- https://master.php.net/note/delete/116554/spam Del: non-english -- https://master.php.net/note/delete/116554/non-english Del: in docs -- https://master.php.net/note/delete/116554/in+docs Del: other reasons-- https://master.php.net/note/delete/116554 Reject -- https://master.php.net/note/reject/116554 Search -- https://master.php.net/manage/user-notes.php
