What are the implications of artificially setting content types in PHP for file downloads?

Setting content types in PHP for file downloads is important for ensuring proper handling of the file by the browser. If the content type is incorrectly set or not set at all, the browser may not know how to handle the file, leading to unexpected behavior or errors. To avoid this, always set the correct content type for the file being downloaded. 

// Set the content type for a PDF file download
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="example.pdf"');

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