PHP Manual: Change the name or location of a file

Description

resource eio_rename(
    string $path,
    string $new_path,
    int $pri = EIO_PRI_DEFAULT,
    callable $callback = NULL,
    mixed $data = NULL
)

eio_rename renames or moves a file to new location.

Parameters

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.

Return Values

eio_rename returns request resource on success, or false on failure.

Examples

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();
?>

The above example will output something similar to:

eio_rename_ok
