Php forces users to download by adding an http response header

In php, you can set the content-type of the header to force the user to download the content, rather than directly open the content in the browser. the following code is implemented: DownloadFile. php $ Filename = $ _ GET ['file']; // Get the fileid from the URL // Query the file ID $ Query = sprintf ("SELECT * FROM tableName WHERE id = '% s'", mysql_real_escape_string ($ filename )); $ SQL = mysql_query ($ query ); If (mysql_num_rows ($ SQL)> 0 ){ $ Row = mysql_fetch_array ($ SQL ); // Set some headers Header ("Pragma: public "); Header ("Expires: 0 "); Header ("Cache-Control: must-revalidate, post-check = 0, pre-check = 0 "); Header ("Content-Type: application/force-download "); Header ("Content-Type: application/octet-stream "); Header ("Content-Type: application/download "); Header ("Content-Disposition: attachment; filename =". basename ($ row ['filename']). ";"); Header ("Content-Transfer-Encoding: binary "); Header ("Content-Length:". filesize ($ row ['filename']); @ Readfile ($ row ['filename']); Exit (0 ); } Else { Header ("Location :/"); Exit; } ?> Files. php Download
