ecco come la invoco:

require_once("../include/db.php");
mysql_select_db($db2,$dbconn) or die (mysql_error()." errore selezione $db2");

function idshopping(){
        $idshopping="";
        for($x=1;$x<=20;$x++){
            $idshopping.=rand(0,9);
        }
        
        $QueryVer=mysql_query("SELECT IDShopping FROm cart WHERE IDShopping='$idshopping'") or die (mysql_error()." errore verifica idshopping in cart");
        if(mysql_num_rows($QueryVer) > 0){
            idshopping();
        }else{
            $QueryVer=mysql_query("SELECT IDShopping FROm shopping WHERE IDShopping='$idshopping'") or die (mysql_error()." errore verifica idshopping in shopping");
            if(mysql_num_rows($QueryVer) > 0){
                idshopping();
            }else{
                $time=(3600 * 24 * 365);
                setcookie("IDShopping_CS",$idshopping,time() + $time,"/");
                return $idshopping;
            }
        }
        mysql_free_result($QueryVer);
}

(!isset($_COOKIE["IDShopping_CS"])) ? $idshopping=idshopping() : $idshopping=$_COOKIE["IDShopping_CS"];
