//create table
     $conforbooknow =new mysqli($mysql_server, $mysql_username, $mysql_password, $mysql_database);

 mysqli_execute_query($conforbooknow, "CREATE TABLE IF NOT EXISTS $mysql_table (ID int(9) NOT NULL auto_increment, `DATESTAMP` DATE, `TIME` VARCHAR(8) NOT NULL DEFAULT '00', `IP` VARCHAR(30) NOT NULL DEFAULT '00', `BROWSER` TINYTEXT, PRIMARY KEY (id))");
