php - mkdir() 未将 chmod 设置为 0777

Question

为什么 mkdir 没有将 CHMOD 设置为 0777 ?

mkdir('/var/www/test', 0777);

创建目录后，CHMOD 设置为 0755
来自 php.net

bool mkdir ( string $pathname [, int $mode = 0777 [, bool $recursive = false [, resource $context ]]] )

$mode应该是 0777默认情况下...但是如果您将第二个参数留空，则 CHMOD 仍设置为 0755

来自 http://php.net/mkdir :

Note: mode is ignored on Windows.

The mode is also modified by the current umask, which you can change using umask().
