eio_rename(3) renames or moves a file to new location. PARAMETERS
o $path - Source path o $new_path - Target path o $pri -The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or NULL.

RETURN VALUES
eio_rename(3) returns request resource on success or FALSE on error. EXAMPLES
Example #1 eio_rename(3) 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 PHP Documentation Group EIO_RENAME(3)
