PHP limits the speed of file download
- // Local file that shocould be sent to the client
- $ Local_file = 'test-file.zip ';
- // Filename that the user gets as default
- $ Download_file = 'your-download-name.zip ';
-
- // Set the download rate limit (=> 20, 5 kb/s)
- $ Download_rate = 20.5;
- If (file_exists ($ local_file) & is_file ($ local_file )){
- // Send headers
- Header ('cache-control: private ');
- Header ('content-Type: application/octet-stream ');
- Header ('content-Length: '. filesize ($ local_file ));
- Header ('content-Disposition: filename = '. $ download_file );
-
- // Flush content
- Flush ();
- // Open file stream
- $ File = fopen ($ local_file, "r ");
- While (! Feof ($ file )){
-
- // Send the current file part to the browser
- Print fread ($ file, round ($ download_rate * 1024 ));
-
- // Flush the content to the browser
- Flush ();
-
- // Sleep one second
- Sleep (1 );
