Is this stupid? Should it be a block or module?  Bottom

    I run a Guild Wars guild site and I was looking for a way to get my guild's current ranking on my site. I didn't really want it in a block because I don't want to clutter up the site or make users have to scroll down twenty times to see all of the blocks I have going on. My solution was to write a Smarty function for my Xanthia theme. I put the following code into the plugins directory of my theme and named it function.smarty.ranking.php

    Code

    function cached_fopen_url($url, $file_mode, $timeout_seconds = 90, $cache_path = "/var/www/dragonsfury/pnTemp", $fsocket_timeout = 10)
    {
            $debug = false;
            clearstatcache();
            $cache_filename=$cache_path . "/" . urlencode($url) .".cached";

            if ($debug) {
                    print "local_cache creation_time =" .
                    @filemtime($cache_filename) .
                    " actual time = " . time() .
                    " timeout = " .
                    timeout_seconds ."<p>";
            }

            if ( ( @file_exists($cache_filename ) and ( ( @filemtime($cache_filename) + $timeout_seconds) > ( time() ) ) ) ) {
                    // ok, file is already cached and young enouth
                    if ($debug) {
                            print "using cached file ($cache_filename) <p>";
                    }
            } else {
                    if ($debug) {
                            print "cacheing file ($url) to local ($cache_filename)<p>";
                    }

                    $urlParts = parse_url($url);
                    $host = $urlParts['host'];
                    $port = (isset($urlParts['port'])) ? $urlParts['port'] : 80;

                    if( !$fp = @fsockopen( $host, $port, $errno, $errstr, $fsocket_timeout )) {
                    // Server not responding
                    } else {
                            if( !fputs( $fp, "GET $url HTTP/1.0\r\nHost:$host\r\n\r\n" )) {
                                    die( "unable to send get request" );
                            }
                            $data = null;
                            stream_set_timeout($fp, $fsocket_timeout);
                            $status = socket_get_status($fp);
                            while( !feof($fp) && !$status['timed_out'])
                            {
                                    $data .= fgets ($fp,8192);
                                    $status = socket_get_status($fp);
                            }
                            fclose ($fp);
                            // strip headers
                            $sData = split("\r\n\r\n", $data, 2);
                            $data = $sData[1];
                            // save to cache file
                            $f2 = fopen($cache_filename,"w+");
                            fwrite($f2,$data);
                            fclose($f2);
                    }
            }
            // ok, point to (fresh) cached file
            if ( @file_exists($cache_filename )) {
                    $handle = fopen($cache_filename, $file_mode);
                    return $handle;
            }
            return false;
    }

    function smarty_function_ranking($params, &$smarty)
    {
            extract($params);
            unset($params);

            $url = "http://ladder.guildwars.com/ladder.dll?name=Dragons+Fury";

            $fp = cached_fopen_url($url, "rb",600);

            $ladderpage = null;

            if($fp) {
                    while(!feof($fp)) {
                            $ladderpage = $ladderpage . fgets($fp, 8192);
                    }
                    fclose($fp);
                    if(preg_match("/>([0-9]{3})<SUP>/S", $ladderpage, $regs)) {
                            $ranking = $regs[1];
                    } else {
                            $ranking = "unavailable";
                    }
            } else {
                    $ranking = "Connection Error";
            }

            $response = "Current guild ranking:&nbsp<a href=\"".$url."\" target=\"new\" style=\"color: ffffff;\"><strong>".$ranking."</strong></a>";

            return $response;
    }


    FYI - I got the caching fopen code from the fopen man page on php.net in the user contributed comments. I added a line to my master.htm, admin.htm, and home.htm modules to include the function in my theme. As you can see, every time someone clicks a link on the page, this function runs. Is this stupid? Is it secure? Should I learn how to write a module and implement it that way? I don't know. Looking for advice on the best way to do this. Keep in mind, I want to implement this as a Smarty function no matter what I do. I don't want another block.
