Tip: Force the browser to show a download dialog

Some times your browser displays the contents of a file rather than giving the user an option to download the file. The code below forces the browser to show a download dialog to the user

<?
	$filename='files/export.csv';
	$length=filesize($filename);
	header("Content-Type: application/csv");		
	header("Content-Length: ".$length);
	header('Content-Disposition: attachment;filename="'.$filename.'"');
	echo file_get_contents($filename);
 ?>
