Use this php code to open a pdf in a new tab
提问by activeDev
I have managed to use the below snippet of code, to open a pdf in a browser.Instead of opening in the same page, I would like it to open in a new browser tab.
我已经设法使用下面的代码片段在浏览器中打开一个 pdf。而不是在同一页面中打开，我希望它在新的浏览器选项卡中打开。
I am not using an tag. This piece of code invokes a number of actions and at the end it is supposed to display the pdf. It works fine, but i would like it to open in a new tab.
我没有使用标签。这段代码调用了许多操作，最后它应该显示 pdf。它工作正常，但我希望它在新选项卡中打开。
Is this possible? and if so could you please explain to me how to do so.
这可能吗？如果可以，请向我解释如何操作。

You can't do that from that request.
你不能从那个请求中做到这一点。
But you can open the link in a new browser window by adding target="_blank" to your a tag, then browsers usually will use a new tab.
但是您可以通过在 a 标签中添加 target="_blank" 来在新的浏览器窗口中打开链接，然后浏览器通常会使用新选项卡。

You can open a new tab while opening your pdf document. Example: if the code that opens your pdf document is on a page called pdfdocument.php, that is some code like so
您可以在打开 pdf 文档的同时打开一个新标签。示例：如果打开您的 pdf 文档的代码位于名为pdfdocument.php的页面上，则是一些类似这样的代码
<?php
`$pdf = file_get_contents($PDFfilename);
header('Content-Type: application/pdf');
header('Cache-Control: public, must-revalidate, max-age=0'); // HTTP/1.1
header('Pragma: public');
header('Expires: Sat, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
header('Content-Length: '.strlen($pdf));
header('Content-Disposition: inline; filename="'.basename($PDFfilename).'";');
ob_clean();
flush();
echo $pdf; `
and you have a link to the page such as http://www.example.com/pdfdocument.php, you can display it in a new tab like so <a href="http://www.example.com/pdfdocument.php" target="_blank"> click here to show pdf preview </a>
并且您有一个指向该页面的链接，例如http://www.example.com/pdfdocument.php，您可以像这样在新选项卡中显示它 <a href="http://www.example.com/pdfdocument.php" target="_blank"> click here to show pdf preview </a>

to open it in other browser tab, you should do it in the html that reference it: <a href="..." target="_blank">Download pdf
要在其他浏览器选项卡中打开它，您应该在引用它的 html 中执行此操作：<a href="..." target="_blank">下载 pdf
回答by Efx
To open it in a new tab if you are using <a>tag you can append a target attribute like this:
如果您使用<a>标签，要在新选项卡中打开它，您可以附加一个目标属性，如下所示：
<a href="your_pdf_generator_link" target="_blank" > TEXT </a>
<a href="your_pdf_generator_link" target="_blank" > TEXT </a>
If you have a button you can apply an inline javascript such as
如果您有按钮，则可以应用内联 javascript，例如
<input type="button" onclick="window.open('your_pdf_generator_link','_blank')" />
<input type="button" onclick="window.open('your_pdf_generator_link','_blank')" />
Hope this helps..
希望这可以帮助..

Just add exit() at the end:
只需在最后添加 exit() ：
$file = $pdf_file_path;
$filename = $file_name;
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
@readfile($file);
exit();
this should just trigger the download of the file.
这应该只是触发文件的下载。
