Force file download in PHP

PHP allows you to change the HTTP headers of files, so that you can force a file to be downloaded that normally the browser would load in the same window. This is perfect for files like PDFs, document files, images, and video that you want your visitors to download rather than read online.

$output = file_get_contents('your_file_here.extension');
if(ini_get('zlib.output_compression'))
{
ini_set('zlib.output_compression', 'Off');
}
$ctype="application/force-download";
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"Your_File_Here.Extension\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".strlen($output));
echo $output;
exit();
