note 109274 added to function.unlink

Be careful. Apparently unlink() has the power to delete entire folders INCLUDING files under some circumstances. Usually functions with a loop are created to actually delete entire folders with files, but today I observed and confirmed that passing a directory name to unlink caused a folder and all images it contained to be deleted. So make sure to use an is_dir() check or other checks to make sure you this doesn't happen to you by accident. This was observed on 5.3.2-1ubuntu4.17. ---- Server IP: 69.147.83.197 Probable Submitter: 122.59.248.227 ---- Manual Page -- http://www.php.net/manual/en/function.unlink.php Edit -- https://master.php.net/note/edit/109274 Del: integrated -- https://master.php.net/note/delete/109274/integrated Del: useless -- https://master.php.net/note/delete/109274/useless Del: bad code -- https://master.php.net/note/delete/109274/bad+code Del: spam -- https://master.php.net/note/delete/109274/spam Del: non-english -- https://master.php.net/note/delete/109274/non-english Del: in docs -- https://master.php.net/note/delete/109274/in+docs Del: other reasons-- https://master.php.net/note/delete/109274 Reject -- https://master.php.net/note/reject/109274 Search -- https://master.php.net/manage/user-notes.php
