index.php 中出错

<?php

//url 形式 index.php?controller=控制器名&method=方法名

require_once('function.php');

$controllerAllow=array('test','index');

$methodAllow=array('test' ,'index' ,'show');

$controller=in_array($_GET['controller'],$controllerAllow) ？daddslashes($_GET['controller']):'index';

$method=in_array($_GET['method'],$methodAllow) ? daddslashes($_GET['method']):'index';

C($controller,$method);

}?>

报错显示在第六行的daddslashes

Parse error: syntax error, unexpected '锛焏addslashes' (T_STRING) in D:\WWW\mvc\index.php on line 6怎么会是这个呢
