What are some common pitfalls when trying to open a PDF in a new window and redirect to a previous page using PHP?

One common pitfall when trying to open a PDF in a new window and redirect to a previous page using PHP is not setting the correct headers for the PDF file. To solve this issue, you need to set the content type header to 'application/pdf' before outputting the PDF content. Additionally, you can use JavaScript to open the PDF in a new window and then redirect the user back to the previous page. 

<?php
// Set the content type header to PDF
header('Content-Type: application/pdf');

// Output the PDF content
readfile('path/to/your/pdf/file.pdf');

// JavaScript to open the PDF in a new window and redirect back to the previous page
echo '<script>window.open("path/to/your/pdf/file.pdf", "_blank"); window.history.back();</script>';
?>
