Re: Binary file copy

Greetings list! Say I want to copy a jpg from a remote server onto mine, using PHP. Right now, my script opens a socket to the remote server, and opens the image file. It copies its contents into a dummy variable, opens a new file on my server, and dumps the contents of the dummy variable into the new file. For reasons I cannot figure out, it is not working the way I want. Rather than display the image, I get an nothing when opening it in an image viewer. Code follows: ------ <?php $ip = '10.10.10.3'; $port = '80'; $h = @fsockopen($ip, $port, $err, $str, 5); if ($h) {

        // Get current image
    $h = @fsockopen($ip, $port, $err, $str, 5);
    $out = "GET /record/current.jpg HTTP/1.1\r\n";
    $out .= "Host: $ip\r\n";
    $out .= "Connection: Close\r\n\r\n";
        fputs($h, $out, strlen($out));
        $data = '';
        while (!feof($h))
    {
        $data .= fgets($h, 128);
    }
            fclose($h);
        // Store to file
    $f = fopen('/path/test.jpg', "wb");
        if ($f)
    {
        fwrite($f, $data, strlen($data));
        fclose($f);
           }
    else
    {
        die('cannot open file for writing');
    }

} else {

    die('cannot contact server');

} ?> --------- I have trimmed the code some, and omitted the part where I remove the HTTP headers and other information I do not need. Why isn't this working for me? Thanks in advance, Jay

in the response you'll be getting the raw http response (including headers); so you're saving them as well thus not a valid image file. can't see why: $image = file_get_contents('http://10.10.10.3/record/current.jpg'); wouldn't work for you.. regardless though if you are using sockets, be sure to trim of that raw http response - oh and look out for chunked or encoded file transfer as well as you'll need to decode etc etc.. (large can of worms - use an http transport class)
