范例

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();
?>

以上例程的输出类似于：

eio_rename_ok
