用户手机号隐藏中间几位

我想将用户发的手机号码显示为132*******2343这种形式，应该怎么在前端怎么改写 :

联系电话：
{php $userid = intval(get_cookie('_userid'));} 
{php $groupid = intval(get_cookie('_groupid'))}   
{if $groupid==0}                                                                       
	未登录无权查看！                                                                       
{elseif $groupid!==4}                                                                 
	高级会员才能查看   
{else}                                                                                
	{$v[phone]}   
{/if}
