There are quite a few options that can be used: (both tested).
有很多选项可以使用：（都经过测试）。
Here are two ways.
这里有两种方法。
header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');
or:(note the escaped double-quotes). The same need to be use when assigning a name to it.
或：（注意转义的双引号）。为其分配名称时也需要使用相同的方法。
<?php
echo "<iframe src=\"file.pdf\" width=\"100%\" style=\"height:100%\"></iframe>";
?>
I.e.: name="myiframe" id="myiframe"
即：name="myiframe" id="myiframe"
would need to be changed to:
需要改为：
name=\"myiframe\" id=\"myiframe\"inside PHP.
name=\"myiframe\" id=\"myiframe\"在 PHP 里面。

Footnote: There are known issues when trying to view PDF files in Windows 8. Installing Adobe Acrobat Reader is a better method to view these types of documents if no browser plug-ins are installed.
脚注：尝试在 Windows 8 中查看 PDF 文件时存在已知问题。如果未安装浏览器插件，安装 Adobe Acrobat Reader 是查看这些类型文档的更好方法。

if(isset($_GET['content'])){
$content = $_GET['content'];
$dir = $_GET['dir'];
header("Content-type:".$content);
@readfile($dir);
}
$directory = (file_exists("mydir/"))?"mydir/":die("file/directory doesn't exists");// checks directory if existing.
//the line above is just a one-line if statement (syntax: (conditon)?code here if true : code if false; )
if($handle = opendir($directory)){ //opens directory if existing.
while ($file = readdir($handle)) { //assign each file with link <a> tag with GET params
echo '<a target="_blank" href="?content=application/pdf&dir='.$directory.'">'.$file.'</a>';
}
}
}
if you click the link a new window will appear with the pdf file
如果您单击链接，将出现一个带有 pdf 文件的新窗口
