): resource

eio_rmdir() removes a directory.

Elenco dei parametri

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

Esempi

Example #1 eio_rmdir() example

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

function my_rmdir_callback($data, $result) {
    if ($result == 0 && !file_exists($data)) {
        echo "eio_rmdir_ok";
    } else if (file_exists($data)) {
        rmdir($data);
    }
}


eio_rmdir($temp_dirname, EIO_PRI_DEFAULT, "my_rmdir_callback", $temp_dirname);
eio_event_loop();
?>

Il precedente esempio visualizzerà qualcosa simile a:

eio_rmdir_ok
