eio_rmdir removes a directory.

Parameter-Liste

path

Directory 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.

Rückgabewerte

Beispiele

Beispiel #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();
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

eio_rmdir_ok
