function download_document( $filename , $path = "" , $mimetype = "application/octet-stream" )
{
header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" );
header( "Content-Disposition: attachment; filename = $filename" );
header( "Content-Length: " . filesize ( $pathto . $filename ));
header( "Content-Type: $mimetype" );
echo file_get_contents ( $pathto . $filename );
}

<?php
$file = "1.txt" ; // 文件的真实地址(支持url,不过不建议用url)
if ( file_exists ( $file )) {
header( 'Content-Description: File Transfer' );
header( 'Content-Type: application/octet-stream' );
header( 'Content-Disposition: attachment; filename=' . basename ( $file ));
header( 'Content-Transfer-Encoding: binary' );
header( 'Expires: 0' );
header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' );
header( 'Pragma: public' );
header( 'Content-Length: ' . filesize ( $file ));
ob_clean();
flush ();
readfile( $file );
exit ;
}
?>
