    mixed $data = NULL
): resource

eio_mkdir() creates directory with specified access mode.

参数

path

Path for the new directory.

Access mode, e.g. 0755

pri

请求的优先级:EIO_PRI_DEFAULTEIO_PRI_MINEIO_PRI_MAXnull。如果是 nullpri 将设为 EIO_PRI_DEFAULT

callback

data

返回值

eio_mkdir() returns request resource on success, 或者在失败时返回 false.

示例

示例 #1 eio_mkdir() example

<?php
$temp_dirname
= "eio-temp-dir";

/* Is called when eio_mkdir() finishes */
function my_mkdir_callback($data, $result) {
if (
$result == 0 && is_dir($temp_dirname)
&& !
is_readable($temp_dirname)
&&
is_writable($temp_dirname)) {
echo
"eio_mkdir_ok";
}

// Remove directory
if (file_exists($data))
rmdir($temp_dirname);
}

// Create directory with access mode 0300
eio_mkdir($temp_dirname, 0300, EIO_PRI_DEFAULT, "my_mkdir_callback", $temp_dirname);
eio_event_loop();
?>

以上示例的输出类似于:

eio_mkdir_ok
