      上兩節我針對guest.php和edit.php作了講述.需要注意的是php和html的區別: 
      php通常是-->(1)<? echo("zihanonline");?> 
                  (2)<? php 
                        echo("zihanonline"); 
                     ?> 
                  (3)<script laanguage="php"> 
                      echo("zihanonline"); 
                     </script> 
                  (4)<% echo("zihanonline");%> 
      等4種方式.不要混淆. 
      下面我們來研究信息管理:manage.php代碼. 
      -----------
