umask

(PHP3 , PHP4 )

umask -- 現在のumaskを変更する

説明

int umask (int mask)

umask()はPHPのumaskをmask & 0777にセットし、 元のumask値を返します。 PHPがサーバ・モジュールとして動作中の場合、各リクエストが 終了するたびにumaskは元の値に戻されます。

umask()を引数無しで実行すると、単に現在の umask値を返します。

umask affects permissions when files and directories are created.

umask is short for "Un-Mask".

So umask is "and"ed with the permissions of mkdir, fopen, etc.

In a sense, the umask setting is "subtracted" from the permissions given to mkdir.

Example:

<PRE>
umask(011);
mkdir('foo', 0777);
</PRE>
will actually make a directory with permissions 0766.

The -S option will print the symbolic values of umask, while changing the umask to the new setting.
(i.e. umask -S 007 will print 'u=rwx,g=rwx,o=')
