What is the significance of determining the Mime/Content type before specifying the Content-Disposition in PHP?

Determining the Mime/Content type before specifying the Content-Disposition in PHP is significant because it ensures that the browser interprets the file correctly. By setting the appropriate Mime type, the browser knows how to handle the file, whether it should display it in the browser window or prompt the user to download it. This helps in avoiding potential issues with file interpretation by the browser. 

// Determine the Mime/Content type
$mime_type = mime_content_type($file_path);

// Set the Content-Disposition header with the correct Mime type
header('Content-Type: ' . $mime_type);
header('Content-Disposition: attachment; filename="' . basename($file_path) . '"');

// Output the file content
readfile($file_path);
