note 104737 added to function.posix-getpwuid

Here's a fairly safe way to get the username from uid even if the posix extension isn't installed. function GetUsernameFromUid($uid) { if (function_exists('posix_getpwuid')) { $a = posix_getpwuid($uid); return $a['name']; } # This works on BSD but not with GNU elseif (strstr(php_uname('s'), 'BSD')) { exec('id -u ' . (int) $uid, $o, $r); if ($r == 0) return trim($o['0']); else return $uid; } elseif (is_readable('/etc/passwd')) { exec(sprintf('grep :%s: /etc/passwd | cut -d: -f1', (int) $uid), $o, $r); if ($r == 0) return trim($o['0']); else return $uid; } else return $uid; } ---- Server IP: 91.199.167.223 Probable Submitter: 80.246.203.133 ---- Manual Page -- http://www.php.net/manual/en/function.posix-getpwuid.php Edit -- https://master.php.net/note/edit/104737 Del: integrated -- https://master.php.net/note/delete/104737/integrated Del: useless -- https://master.php.net/note/delete/104737/useless Del: bad code -- https://master.php.net/note/delete/104737/bad+code Del: spam -- https://master.php.net/note/delete/104737/spam Del: non-english -- https://master.php.net/note/delete/104737/non-english Del: in docs -- https://master.php.net/note/delete/104737/in+docs Del: other reasons-- https://master.php.net/note/delete/104737 Reject -- https://master.php.net/note/reject/104737 Search -- https://master.php.net/manage/user-notes.php
