= NULLeio_rename() renames or moves a file to new location.
path
Source path
new_path
Target path
pri
请求的优先级:EIO_PRI_DEFAULT
,EIO_PRI_MIN
,EIO_PRI_MAX
或 null
。如果是
null
,pri
将设为
EIO_PRI_DEFAULT
。
callback
callback
函数在请求完成时被调用。其应匹配一下原型:
void callback(mixed $data, int $result[, resource $req]);
data
传递给请求的用户数据。
result
针对请求的结果的值。通常是相应的系统调用返回的值。
req
可选的请求资源,可被 eio_get_last_error() 之类的函数使用。
data
Arbitrary variable passed to callback
.
eio_rename() returns request resource on success, 或者在失败时返回 false
.
示例 #1 eio_rename() example
<?php
$filename = dirname(__FILE__)."/eio-temp-file.dat";
touch($filename);
$new_filename = dirname(__FILE__)."/eio-temp-file-new.dat";
function my_rename_cb($data, $result) {
global $filename, $new_filename;
if ($result == 0 && !file_exists($filename) && file_exists($new_filename)) {
@unlink($new_filename);
echo "eio_rename_ok";
} else {
@unlink($filename);
}
}
eio_rename($filename, $new_filename, EIO_PRI_DEFAULT, "my_rename_cb", $filename);
eio_event_loop();
?>
以上示例的输出类似于:
eio_rename_ok
