How can PHP scripts be used to securely manage access to PDF files in a folder?

To securely manage access to PDF files in a folder using PHP scripts, you can create a script that checks if the user is authenticated before allowing them to download the file. This can be done by storing the PDF files outside of the web root directory and using PHP to serve the files only to authenticated users. 

<?php
// Check if user is authenticated
if($_SESSION['authenticated']) {
  $file = 'path/to/pdf/file.pdf';
  
  // Check if file exists
  if(file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/pdf');
    header('Content-Disposition: inline; filename="' . basename($file) . '"');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
  } else {
    echo 'File not found.';
  }
} else {
  echo 'Access denied.';
}
?>
