note 107581 modified in function.header by danbrown

To use header() with 'content-type', why don't you use mime_content_type() function rather than checking the type on the basis of extension?
Example code:

<?php
$file="test.docx";
header("Pragma: public");
header('Content-disposition: attachment; filename='.$file);
header("Content-type: ".mime_content_type($file));
header('Content-Transfer-Encoding: binary');
ob_clean(); 
flush(); 
readfile($file);
?>

Use $file to map to whichever type of file.
Note: the mime types should already be defined in apache settings --was-- To use header() with 'content-type', why don't you use mime_content_type() function rather than checking the type on the basis of extension?
