Read the docs. ------------------------------------------------------------------------ [2018-08-03 11:44:29] spam2 at rhsoft dot net the umask is for control default permission while the topic is explicit one! mkdir also has a problem with permissions when create a recursive directory tree ------------------------------------------------------------------------ [2018-08-03 10:33:46] requinix@php.net What's your umask? ------------------------------------------------------------------------ [2018-08-03 10:20:05] zoeslam at gmail dot com Description: ------------ mkdir($dir, 0770) skips group write permission https://3v4l.org/pKu4U Test script: --------------- $dir = uniqid('/tmp/test_0700_'); mkdir($dir, 0700); $fileperms = 0777 & fileperms($dir); var_dump(0700 === $fileperms); var_dump(decoct($fileperms)); $dir = uniqid('/tmp/test_0770_'); mkdir($dir, 0770); $fileperms = 0777 & fileperms($dir); var_dump(0770 === $fileperms); var_dump(decoct($fileperms)); Expected result: ---------------- bool(true) string(3) "700" bool(true) string(3) "770" Actual result: -------------- bool(true) string(3) "700" bool(false) string(3) "750" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76698&edit=1
