This may not be exactly what you're looking for - but it could be
modified fairly
easily. it uses HTTP headers to find the file size (content-length) and
then does an fread (not fgetc!). should work for any file transmitted
via HTTP.

<?
        $gotheaders = False;
        $headerlen = 0;
        $fp = fsockopen("localhost", 80);
        if ($fp > 0) {
                fputs($fp, "GET /index.html HTTP/1.0\n\n");
                while (!feof($fp) && !$gotheaders) {
                        $buf = fgets($fp, 1024);
                        $headerlen += strlen($buf);
                        if (strstr(strtolower($buf), "content-length"))
{
                                $clen = $buf;
                        }
                        if (strstr(strtolower($buf), "content-type")) {
                                $gotheaders = True;
                                $buf = fgets($fp, 1024);
                                $headerlen += strlen($buf);
                                $buf = fgets($fp, 1024);
                                $headerlen += strlen($buf);
                        }
                }
                
                if ($gotheaders) {
                        $foo = strtok($clen, ":");
                        $n = strtok(":");
                        trim(&$n);
                        $len = Intval($n);
                        $data = fread($fp, $len);
                }
                fclose($fp);
        }

        echo $data;
?>
