note 61331 added to function.is-writable

It appears that is_writable() does not check full permissions of a file to determine whether the current user can write to it. For example, with Apache running as user 'www', and a member of the group 'wheel', is_writable() returns false on a file like -rwxrwxr-x root wheel /etc/some.file ---- Server IP: 64.71.164.2 Probable Submitter: 64.147.100.2 ---- Manual Page -- http://www.php.net/manual/en/function.is-writable.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61331 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61331&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61331&report=yes Search -- http://master.php.net/manage/user-notes.php
