我试图让这段代码的工作,但由于某些原因,所有的回波的能够输出正确的内容,但没有头似乎不想强制下载我的文档。接下来是我正在尝试构建的用于文件下载的文件。它被设置为输入如下代码:downloader.php?f=13&t=doc
根据用户权限从两个文件夹之一下载名为201-xxx.doc
或201-xxx.pdf
的文件。PHP READFILE()不是为我工作,我不知道为什么
所有的逻辑工作到底部的标题信息。如果我注释掉标题内容类型和标题内容处置,那么它会将文件读入浏览器。和这两个行在内,它给我,说"Error 6 (net::ERR_FILE_NOT_FOUND): The file or directory could not be found."

请帮助,因为我一直在这个整天感到困惑没有结束,为什么这是行不通的错误。 Filesize()拉正确的长度,所以我知道我正在看的路径中有一个文件。 (我也是PHP新手,所以如果有什么我不见了,请分享。)
在此先感谢!
使用'is_readable()'而不是'file_exists()'会更安全。 is_readable既能确保文件存在,又能读取文件。有很多文件存在,但无法读取。另外,当你调用readfile时,'$ file_path'中有什么? –
刚刚看到这个评论/问题。我切换到'is_readable()',它仍然会抛出错误。当我取消注释$ file_path时,它会回应这个:'/ home5/[我的主机帐户]/public_html/1hoefl4priaspoafr/ex/201-015.pdf'这是该文件的正确目录。大文件的 – Crazycoolcam
