范例
Example #1 eio_mkdir() example
<?php$temp_dirname = "eio-temp-dir";/* Is called when eio_mkdir() finishes */function my_mkdir_callback($data, $result) { if ($result == 0 && is_dir($temp_dirname) && !is_readable($temp_dirname) && is_writable($temp_dirname)) { echo "eio_mkdir_ok"; } // Remove directory if (file_exists($data)) rmdir($temp_dirname);}// Create directory with access mode 0300eio_mkdir($temp_dirname, 0300, EIO_PRI_DEFAULT, "my_mkdir_callback", $temp_dirname);eio_event_loop();?>
以上例程的输出类似于:
eio_mkdir_ok
