[twitter-dev] track syntax

[Joseph]

I am trying to use the track streaming API, but I'm having trouble
with the syntax. The example shows how to use a tracking list stored
in a file in the format: track = word1, word2, etc..

I tried the following (following a successful fsockopen call to
stream.twitter.api:

POST /track.json track = Palin, #fubar HTTP/1.1 Host:
stream.twitter.com User-Agent: UserAgent Authorization: Basic
cGXybmFzc3TzZGV2OlBhcm5hMzT1Mzl4MDMz Connection: Close

and I am getting the following error code: HTTP/1.1 400 Bad Request

The actual relevant test PHP code is:

$fp = fsockopen($url, 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)\n";
} else {
    echo "file handle: ".$fp."<br/>";
    $header = "POST /track.json track = $trackTerms HTTP/1.1\r\n";
    $header .= "Host: stream.twitter.com\r\n";
    $header .= "User-Agent: UserAgent\r\n";
    $header .= "Authorization: Basic " . base64_encode($twitUsername .
':' . $twitPwd)."\r\n";
    $header .= "Connection: Close\r\n\r\n";
    echo $header."<br/>";
    fwrite($fp, $header);
    $line = fgets($fp, 4096);
    echo $line;
    fclose($fp);
}
