you can use PDF Mergerlibrary to achive your goals.
Here is the link to original library (outdated). Prefer myokyawhtun fork which is maintained
您可以使用PDF Merger库来实现您的目标。
这是原始库（已过时）的链接。更喜欢维护的 myokyawhtun 叉子
and a sample code will be as following
示例代码如下
include 'PDFMerger.php';
$pdf = new PDFMerger;
$pdf->addPDF('path_to_pdf/one.pdf', '1, 3, 4') //include file1 - pages 1,3,4
->addPDF('path_to_pdf/two.pdf', '1-2') //include file2 - pages 1 to 2
->addPDF('path_to_pdf/three.pdf', 'all') //include file3 - all pages
->merge('browser', 'test.pdf'); // OUTPUT : make sure you choose browser mode here.
Supported modes- browser, file, downloadand string.
支持的模式- ，，和。browserfiledownloadstring
Edit: As i can see you have tagged CI you can put PDFMerger.phpin applications/libraries.
and load it in autoload.phpor in controller
编辑：我可以看到你所标记CI，你可以把PDFMerger.php在applications/libraries。并将其装入autoload.php或装入controller
and then can use it like $this->pdfmerger->addPDF()and merge()functions.
然后可以像$this->pdfmerger->addPDF()和merge()功能一样使用它。

Instead of using
而不是使用
@readfile($file);
Use
用
echo file_get_contents($file);
Or ommit the @
或者省略 @

This method works if you want to display a pdf in the browser page.
如果您想在浏览器页面中显示 pdf，则此方法有效。
$file = 'filename.pdf';
echo "<embed src='$file' type='application/pdf' width='80%' height='600px' />";

Friends just use Anchor Tag that's it. Now-day's all newer browsers supports view of any files.
朋友只需使用Anchor Tag就可以了。现在所有较新的浏览器都支持查看任何文件。
