<?
$value ='oicq';
$array = array(20,25,26);
$aid = $array[mt_rand(0,2)];
echo $aid;
if( empty( $_COOKIE["cook"] ) )

下面為js cookie

<SCRIPT type=text/javascript> 
function Set(Cookie_name)  
{  
 var Then = new Date()  
 Then.setTime(Then.getTime() + 1*3600000 ) //小時  
 document.cookie = Cookie_name+"=true;expires="+ Then.toGMTString()  
}  
function Get(Cookie_name)  
{  
 var cookieString = new String(document.cookie)  
 var cookieHeader = Cookie_name+"="  
 var beginPosition = cookieString.indexOf(cookieHeader)  
 if (beginPosition != -1) //cookie已經設置值,應該 不顯示提示框  
 {  
   alert(Cookie_name+"返回"+cookieString.substring(beginPosition + cookieHeader.length));  
 }  
 else //cookie沒有設置值,應該顯示提示框  
 {  
  alert("Cookie 未找到!");  
 }  
}  
function Move(Cookie_name)  
{  
 document.cookie = Cookie_name+"=;expires=Fri, 02-Jan-1970 00:00:00 GMT";  
}  
</SCRIPT> 
<P> 
<INPUT onclick="Set('steven lu')" type=button value=設置cookie值><P>
