请问一下thinkphp模板使用函数的问题
我想把ip最后一位替换成*我用的如下方式
{$vo.ip|preg_replace='/((?:\d+\.){3})\d+/','\\1*',###}
提示错误
Parse error: syntax error, unexpected ':' in C:\wamp\www\guestbook\guestbook\Runtime\Cache\Guestbook\b5add68846b03533035d53dc5ca1074b.php on line 34望高手解答,还有就是我会输出之前替换不用告诉我输出之前怎样替换,我就是想知道模板输出时是怎样替换的,谢谢。

$str=preg_replace("/\->\w+$/", "", $_GET['name']);
