Elenco dei parametri

path

Source path

new_path

Target path

pri

The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or null. If null passed, pri internally is set to EIO_PRI_DEFAULT.

callback

callback function is called when the request is done. It should match the following prototype:

void callback(mixed $data, int $result[, resource $req]);

data: is custom data passed to the request.
result: request-specific result value; basically, the value returned by corresponding system call.
req: is optional request resource which can be used with functions like eio_get_last_error().

data

Arbitrary variable passed to callback.

Valori restituiti

eio_rename() returns request resource on success, o false in caso di fallimento.

Esempi

Example #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();
?>

Il precedente esempio visualizzerà qualcosa simile a:

eio_rename_ok
