Limit Download Speed

[IFeelYourPain]

Is there a way to limit download speed via a single page?

i.e. My download page is download.php and my files are stored in /attachments which is one directory above the file?

I want to use php however though because I need to run conditionals which exclude certain members of my website. Maybe htaccess in the directory and php code in the download page?

Well let's see...

I googled, found this site:
http://bytes.com/topic/php/answers/3...download-speed

and then found this code:

PHP Code:

<?php 
function send_file($file, $speed = 100) { 
  
    //First, see if the file exists   
    if (!is_file($file)) { 
        die("<b>404 File not found!</b>"); 
    }   
    //Gather relevent info about file 
    $filename = basename($file); 
    $file_extension = strtolower(substr(strrchr($filename,"."),1)); 
    // This will set the Content-Type to the appropriate setting for the file 
    switch( $file_extension ) { 
        case "exe": 
            $ctype="application/octet-stream"; 
            break; 
        case "zip": 
            $ctype="application/zip"; 
            break;

            break; 
  
        //  The following are for extensions that shouldn't be downloaded 
        // (sensitive stuff, like php files)

        case "html": 
        case "txt": 
            die("<b>Cannot be used for ". $file_extension ." files!</b>"); 
            break; 
        default: 
            $ctype="application/force-download"; 
    } 
  
    //  Begin writing headers 
    header("Cache-Control:"); 
    header("Cache-Control: public"); 
    header("Content-Type: $ctype"); 
  
    $filespaces = str_replace("_", " ", $filename); 
    // if your filename contains underscores, replace them with spaces 
  
    $header='Content-Disposition: attachment; filename='.$filespaces; 
    header($header); 
    header("Accept-Ranges: bytes"); 
  
    $size = filesize($file);   
    //  check if http_range is sent by browser (or download manager)   
    if(isset($_SERVER['HTTP_RANGE'])) { 
        // if yes, download missing part      
  
        $seek_range = substr($_SERVER['HTTP_RANGE'] , 6); 
        $range = explode( '-', $seek_range); 
        if($range[0] > 0) { $seek_start = intval($range[0]); } 
        if($range[1] > 0) { $seek_end  =  intval($range[1]); } 
  
        header("HTTP/1.1 206 Partial Content"); 
        header("Content-Length: " . ($seek_end - $seek_start + 1)); 
        header("Content-Range: bytes $seek_start-$seek_end/$size"); 
    } else { 
        header("Content-Range: bytes 0-$seek_end/$size"); 
        header("Content-Length: $size"); 
    }   
    //open the file 
    $fp = fopen("$file","rb"); 
  
    //seek to start of missing part   
    fseek($fp,$seek_start); 
  
    //start buffered download 
    while(!feof($fp)) {       
        //reset time limit for big files 
        set_time_limit(0);       
        print(fread($fp,1024*$speed)); 
        flush(); 
        sleep(1); 
    } 
    fclose($fp); 
    exit; 
} 
?>

Have you tried any of these steps yet?

Nope haven't seen this?

What data is $file pulling from? Cause most of them you have a preset file like $file = 'file.rar';

I just want it so my attachments.php will make all downloads on that page be like 200 kbps.

[Rowsdower!]

You could set $file based on a session variable or a $_GET (written into the URL - good for direct linking or bookmarking) or $_POST (passed invisibly through the backend - not so good for direct linking or bookmarking) variable without any trouble at all. That would keep things dynamic enough to work for any file you are offering for download.

I'm confused.

[Rowsdower!]

Which part are you confused about? Do you know what session variables and $_GET variables are?

Yea they are used n form submissions right?

[Rowsdower!]

They can be used in forms but they don't HAVE to be. In fact $_POST variables are more common for forms than $_GET variables are.

You should take some time to actually read about sessions, session variables, and $_GET variables (and $_POST variables while you're at it).

If you are just waiting for me to spoon-feed you the answer then you are in for a loooong wait.
