The relationship between PHP's cookie and JavaScript cookie

PHP read-write cookie statement:

Setcookie ("User", "Lilu", Time () +3600); Echo $_cookie["user"];

JavaScript read-write cookie code:

function Setcookie (name,value)//two parameters, one is the name of the cookie, one is the value {    var days = 30;//This cookie will be saved for 30 days    var exp  = new Date ();    New Date ("December, 9998");    Exp.settime (Exp.gettime () + days*24*60*60*1000);    Document.cookie = name + "=" + Escape (value) + "; expires=" + exp.togmtstring ();} function GetCookie (name)//Take cookie function        {    var arr = document.cookie.match (New RegExp ("(^|)" +name+ "= ([^;] *)(;|$)"));     if (arr! = null) return unescape (arr[2]); return null;} function Delcookie (name)//delete cookie{    var exp = new Date ();    Exp.settime (Exp.gettime ()-1);    var cval=getcookie (name);    if (cval!=null) document.cookie= name + "=" +cval+ "; expires=" +exp.togmtstring ();} Setcookie ("Lilu", "It's Me") Alert (GetCookie (' Lilu '));
