To enable users to download a PDF file without automatically opening it, utilize the Content-Disposition header.
It is important to use this feature sparingly and only when absolutely necessary for the user experience. Do not force users to download files if they simply intend to view them online, as this may be frustrating for them.
Here is the code snippet for a PHP file named "a.php":
<?php
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename=file.pdf')
echo file_get_contents("file.pdf");
?>
To link it in a web page, use the following HTML code:
<a href="a.php">Download</a>
Did you know that there is a little-known HTML 5 solution to this common issue?
<a href="./folder/document.pdf" download="newname">Click here to download the PDF</a>
You can specify a suggested filename for the user to save the file as by replacing "newname" with your desired name. If left empty, it will default to the filename on the server side like this:
<a href="./folder/document.pdf" download>Click here to download the PDF</a>

Trying to manipulate browser behavior is quite complex.
Your best option would be to redirect the link to appear as though it leads to a webpage (e.g., download.php?file=1), and when the browser detects it as binary data, it will prompt the user for action. This approach should likely achieve the desired result.
Keep in mind that this outcome is not guaranteed and heavily relies on individual browser settings.
