mkdir
(PHP 4, PHP 5)
mkdir — Makes directory
說明
bool mkdir
( string $pathname
[, int $mode
[, bool $recursive
[, resource $context
]]] )
Attempts to create the directory specified by pathname.
參數
- pathname
-
The directory path.
- mode
-
The mode is 0777 by default, which means the widest possible access. For more information on modes, read the details on the chmod() page.
Note: mode is ignored on Windows.
Note that you probably want to specify the mode as an octal number, which means it should have a leading zero. The mode is also modified by the current umask, which you can change using umask().
- recursive

- context

Note: 對 context 的支援是 PHP 5.0.0 增加的。有關 context 的說明見Streams。
Return值
如果成功則回傳 TRUE，失敗則回傳 FALSE。

Note: 當安全模式被啟用時，PHP 將檢查被操作的目錄是否和正在執行的腳本有相同的 UID（擁有者）。
