note 104149 added to function.posix-setgid

if you're going to use this along with posix_setuid, make sure you call posix_setgid first: define (PROC_USER, 'john'); define (PROC_GRP, 'admins'); following works: $user = posix_getpwnam( PROC_USER ); $group = posix_getgrnam( PROC_GRP); echo posix_getuid()."\n"; echo posix_getgid()."\n"; posix_setgid($group['gid']); posix_setuid($user['uid']); echo posix_getuid()."\n"; echo posix_getgid()."\n"; following will not set gid $user = posix_getpwnam( PROC_USER ); $group = posix_getgrnam( PROC_GRP); echo posix_getuid()."\n"; echo posix_getgid()."\n"; posix_setuid($user['uid']); posix_setgid($group['gid']); echo posix_getuid()."\n"; echo posix_getgid()."\n"; ---- Server IP: 69.147.83.197 Probable Submitter: 12.234.36.130 ---- Manual Page -- http://www.php.net/manual/en/function.posix-setgid.php Edit -- https://master.php.net/note/edit/104149 Del: integrated -- https://master.php.net/note/delete/104149/integrated Del: useless -- https://master.php.net/note/delete/104149/useless Del: bad code -- https://master.php.net/note/delete/104149/bad+code Del: spam -- https://master.php.net/note/delete/104149/spam Del: non-english -- https://master.php.net/note/delete/104149/non-english Del: in docs -- https://master.php.net/note/delete/104149/in+docs Del: other reasons-- https://master.php.net/note/delete/104149 Reject -- https://master.php.net/note/reject/104149 Search -- https://master.php.net/manage/user-notes.php
