How can htaccess files be properly configured to differentiate between PDF files and other file formats in PHP?

To properly configure htaccess files to differentiate between PDF files and other file formats in PHP, you can use the RewriteCond directive to check the file extension of the requested file. If the file extension is ".pdf", you can set a custom header or perform a specific action in PHP based on this condition. ```apache RewriteEngine On RewriteCond %{REQUEST_URI} \.pdf$ RewriteRule ^ - [E=PDF_FILE:true] ``` In your PHP code, you can then check for the presence of the custom header "PDF_FILE" to determine if the requested file is a PDF file. 

if (isset($_SERVER['PDF_FILE']) && $_SERVER['PDF_FILE'] == 'true') {
    // This is a PDF file
    // Perform specific actions for PDF files
} else {
    // This is not a PDF file
    // Handle other file formats
}
