在php中打开文件（pdf、word、excel）（使用mysql数据库）

php mysql

在php中打开文件（pdf、word、excel）（使用mysql数据库）,php,mysql,Php,Mysql,我不熟悉php和mysql。我创建了一个用于上载文件的php页面，这些文件保存到我的本地驱动器。在另一个页面中，当用户选择一个选项时，与该选项相关的文件将以表格格式显示。一列将链接到本地驱动器中的文件。至此，我成功。问题是，当点击文件超链接时，没有显示任何内容。但是，当我复制文件的地址链接并粘贴到新窗口时，它正在打开。请帮助我，我被问题卡住了两周。为了进行实验，我创建了一个简单的php文件，只是为了看看超链接是否正常工作。但没有成功。我将在这里粘贴我使用过的轨迹 <?php echo

应该很明显-当你的链接说打开文件C:/stuff/stuff.txt时，用户的浏览器将尝试在其计算机上的此位置查找文件…您只需要了解如何使用php@dcoder：。目前我正在使用我的系统。我正在尝试访问存储在我正在工作的笔记本电脑上的文件。它仍在工作。@学习者我想像excel一样打开保存的文件，word等。就像在powerpoint中使用超链接打开文件一样。我希望使用phpI的相同功能可以提醒您需要验证文件名。您不希望您的服务器允许人们从您的系统下载任何文件。您应该将其限制为公共目录。实际上，要求用户将文件上载到公用系统上的公用文件夹。在另一个网页上会显示文件。任何访问此网页的人都需要打开此文件。此文件仅在本地网络Intranet上。正如我已经说过的，除单击超链接时打开文件。@barmar。我已尝试过该代码。它对pdf工作正常。但对图像或word无效。请向我提供通过超链接打开文件的完整工作代码。非常感谢。什么不起作用？它不是下载文件，还是下载类型错误？如果是后者，请参阅mime内容类型的文档，可能您需要更新某些配置。它正在下载文件。但下载的文件为空。其中没有任何内容。例如，对于图像，它显示没有可用预览。我不能在不下载的情况下打开文件。
