ばかげた問題が発生しています。特定のバイト数を取得してから、接続を閉じる必要があります。ヘッダーから「コンテンツの長さ」を抽出し、その長さを使用して、接続を切断する前に取得する必要のあるバイト数を決定できることがわかりました。しかし、私は間違いを犯したようです。（本来あるべき）2428ではなく、40バイトしか取得していません。おそらく私はfgets（）を正しく使用していませんか？
コードは次のとおりです。
private static function Send($URL, $Data) {
$server = parse_url($URL, PHP_URL_HOST);
$port = parse_url($URL, PHP_URL_PORT);
// If the parsing the port information fails, we will assume it's on a default port.
// As such, we'll set the port in the switch below.
if($port == null) {
switch(parse_url($URL, PHP_URL_SCHEME)) {
case "HTTP":
$port = 80;
break;
case "HTTPS":
$port = 443;
break;
}
}
// Check if we are using a proxy (debug configuration typically).
if(\HTTP\HTTPRequests::ProxyEnabled) {
$server = \HTTP\HTTPRequests::ProxyServer;
$port = \HTTP\HTTPRequests::ProxyPort;
}
// Open a connection to the server.
$connection = fsockopen($server, $port, $errno, $errstr);
if (!$connection) {
die("OMG Ponies!");
}

なぜ私はそれをこのようにしているのですか？どうやら、私はある種のタイムアウトエラーに遭遇していました。これにより、各接続が30秒間開いたままになります（はい、30秒全体）。そこで、正確なバイト数を取得して閉じるためにこのコードを記述しました。どんな助けでも大歓迎です。
