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

← eio_realpath
