What are the considerations when reversing the logic of mod_rewrite rules for PDF file redirection in PHP?

When reversing the logic of mod_rewrite rules for PDF file redirection in PHP, the key consideration is to ensure that the requested PDF files are being served correctly. This can be achieved by checking if the requested file exists in the specified directory and then redirecting the user to that file if it does. Additionally, it is important to handle any errors or edge cases that may arise during the redirection process. 

<?php
// Get the requested PDF file from the URL
$pdf_file = $_SERVER['REQUEST_URI'];

// Specify the directory where the PDF files are stored
$pdf_directory = '/path/to/pdf/files/';

// Check if the requested PDF file exists in the specified directory
if (file_exists($pdf_directory . $pdf_file)) {
    // Serve the PDF file to the user
    header('Content-Type: application/pdf');
    readfile($pdf_directory . $pdf_file);
    exit;
} else {
    // Handle error if the requested PDF file does not exist
    echo 'Error: PDF file not found';
}
?>
