cookie的问题

Question

SetCookie("CookieArray", "Value 1"); 
SetCookie("CookieArray", "Value 2"); 
SetCookie("CookieArray", "Value 3"); 
SetCookie("CookieArray", "Value 4");
cookiearray就是cookie的名称。而后面的就是保存的值setcookie ($cookie_name."[1]",$username,time()+(1*24*3600));
setcookie ($cookie_name."[2]",$password,time()+(1*24*3600));
setcookie ($cookie_name."[shuku]",$user_shuku,time()+(1*24*3600));
setcookie ($cookie_name."[shuxiu]",$user_shuxiu,time()+(1*24*3600));
setcookie ($cookie_name."[shushan]",$user_shushan,time()+(1*24*3600));
setcookie ($cookie_name."[shushu]",$user_shushu,time()+(1*24*3600));
setcookie ($cookie_name."[shucha]",$user_shucha,time()+(1*24*3600));
setcookie ($cookie_name."[shutong]",$user_shutong,time()+(1*24*3600));
setcookie ($cookie_name."[shujiao]",$user_shujiao,time()+(1*24*3600));
setcookie ($cookie_name."[xiushu]",$user_xiushu,time()+(1*24*3600));

setcookie ($cookie_name."[suoshu]",$user_suoshu,time()+(1*24*3600));
setcookie ($cookie_name."[chushu]",$user_chushu,time()+(1*24*3600));
setcookie ($cookie_name."[dashu]",$user_dashu,time()+(1*24*3600));
setcookie ($cookie_name."[jiaoxiu]",$user_jiaoxiu,time()+(1*24*3600));
setcookie ($cookie_name."[beishu]",$user_beishu,time()+(1*24*3600));
setcookie ($cookie_name."[huishu]",$user_huishu,time()+(1*24*3600));
setcookie ($cookie_name."[yongguan]",$user_yongguan,time()+(1*24*3600)); 这是我的一个原吗，cookie_name 就是名称，后面的是里面的值
