eio_rename — Change the name or location of a file
$path,$new_path,$pri = EIO_PRI_DEFAULT,$callback = NULL,$data = NULLeio_rename() renames or moves a file to new location.
pathSource path
new_pathTarget path
pri請(qǐng)求的優(yōu)先級(jí):EIO_PRI_DEFAULT,EIO_PRI_MIN,EIO_PRI_MAX 或 null。如果是
null,pri 將設(shè)為
EIO_PRI_DEFAULT。
callback
callback
函數(shù)在請(qǐng)求完成時(shí)被調(diào)用。其應(yīng)匹配一下原型:
void callback(mixed $data, int $result[, resource $req]);
data傳遞給請(qǐng)求的用戶數(shù)據(jù)。
result針對(duì)請(qǐng)求的結(jié)果的值。通常是相應(yīng)的系統(tǒng)調(diào)用返回的值。
req可選的請(qǐng)求資源,可被 eio_get_last_error() 之類(lèi)的函數(shù)使用。
data
Arbitrary variable passed to callback.
eio_rename() returns request resource on success, 或者在失敗時(shí)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();
?>
以上例程的輸出類(lèi)似于:
eio_rename_ok
