PHP开发简单图书后台管理系统top页面

图书后台管理系统需要不同的页面来展示不同的功能效果

最后将这些页面组装起来，形成完整的后台功能页面。

这一节我们将创建后台管理系统的头部页面

如图所示，包含了管理员修改密码，用户信息，退出本系统

显示首页，页面前进，后退，刷新，帮助等点击按键

使用<table>标签，用<tr><td>进行布局。

在加上各种小图标。来实现效果。

布局分为3个<table>段落

第一个为修改密码，用户信息和退出系统

<tr>
  <td height="57" background="https://img.php.cn/upload/course/000/000/008/58241d480ee8f976.gif">
    <table width="100%" border="0" cellspacing="0" cellpadding="0">

        <td>&nbsp;</td>
        <td width="281" valign="bottom"><table width="100%" border="0" cellspacing="0" cellpadding="0">
            <tr>
              <td width="33" height="27"><img src="https://img.php.cn/upload/course/000/000/008/58241db991188465.gif" width="33" height="27" /></td>

                    </td>
                    <td><div align="right"><a href="ly_pwd.php" target="rightFrame">

                    </td>
                  </tr>
                </table></td>
            </tr>
          </table>
        </td>
      </tr>
    </table>
  </td>
</tr>

第二部分为首页，前进，后退，刷新，帮助等点击按键。

<tr>
  <td height="40" background="https://img.php.cn/upload/course/000/000/008/58241fee34c77371.gif">
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>

          </table></td>
        <td width="248" background="https://img.php.cn/upload/course/000/000/008/5824211aae974497.gif">
        <table width="100%" border="0" cellspacing="0" cellpadding="0">

              <td width="9%">&nbsp;</td>
            </tr>
          </table>
        </td>
      </tr>
    </table>
  </td>

第三部分为管理菜单显示

<tr>
  <td height="30" background="https://img.php.cn/upload/course/000/000/008/5824213c382a3310.gif">
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td width="8" height="30"><img src="https://img.php.cn/upload/course/000/000/008/5824215c09227277.gif" width="8" height="30" /></td>
        <td width="35%" background="https://img.php.cn/upload/course/000/000/008/5824217ae53db193.gif">
          <table width="100%" border="0" cellspacing="0" cellpadding="0">
            <tr>
              <td width="24%"> </td>
              <td width="53%" height="20" valign="bottom" class="STYLE1">管理菜单</td>
              <td width="33%"> </td>
            </tr>
          </table>
        </td>
        <td><img src="https://img.php.cn/upload/course/000/000/008/58242199adc1e244.gif" height="30" /></td>
        <td><table width="100%" border="0" cellspacing="0" cellpadding="0">

              <td valign="bottom" class="STYLE1"><div align="right"></div></td>
            </tr>
          </table>
        </td>
        <td width="17"><img src="https://img.php.cn/upload/course/000/000/008/582421be84fc5175.gif" width="17" height="30" /></td>
      </tr>
    </table></td>
</tr>

这样结合起来我们就完成了后台管理头部页面的的前端代码。
