note 79889 added to function.is-dir

One note regarding checking for empty directories : >>echo (count(glob("$dir/*")) === 0) ? 'Empty' : 'Not empty'; This does not work correctly on Linux. The '.' and '..' will always be returned even if no files are present in the directory. ---- Server IP: 83.137.20.135 Probable Submitter: 195.73.82.12 ---- Manual Page -- http://www.php.net/manual/en/function.is-dir.php Edit -- https://master.php.net/note/edit/79889 Del: integrated -- https://master.php.net/note/delete/79889/integrated Del: useless -- https://master.php.net/note/delete/79889/useless Del: bad code -- https://master.php.net/note/delete/79889/bad+code Del: spam -- https://master.php.net/note/delete/79889/spam Del: non-english -- https://master.php.net/note/delete/79889/non-english Del: in docs -- https://master.php.net/note/delete/79889/in+docs Del: other reasons-- https://master.php.net/note/delete/79889 Reject -- https://master.php.net/note/reject/79889 Search -- https://master.php.net/manage/user-notes.php
