さて、キャプチャを設定しようとしていますが、このコードを入れると壊れます。

if(isset($_POST["captcha"]))
    if($_SESSION["captcha"]==$_POST["captcha"])

それなしでそれを行うと、ページは機能しますが、キャプチャによって誤った送信が行われます。

解析エラー: 構文エラー、予期しない '"'、71 行目の /hermes/waloraweb085/b2027/moo.lutarinet/jointest.php で T_STRING または T_VARIABLE または T_NUM_STRING が必要です

あなたが行方不明ですEND;：

END; // You forgot to include this

ちなみに、session_start()他の出力が開始される前に実行する必要があるため、スクリプトで最初に呼び出す必要があります。

また、複数行のブランチを使用して中かっこを整理するようにしてください (スキャンしやすくなります)。

if (isset($_POST["captcha"]))
{
    if ($_SESSION["captcha"] == $_POST["captcha"])
    {
        //CAPTHCA is valid; proceed the message: save to database, send by e-mail ...
        echo 'CAPTHCA is valid; proceed the message';
    }
    else
    {
        echo 'CAPTHCA is not valid; ignore submission';
    }
}

if(isset($_POST["captcha"]))
if($_SESSION["captcha"]==$_POST["captcha"])
{
    //CAPTHCA is valid; proceed the message: save to database, send by e-mail ...
echo 'CAPTHCA is valid; proceed the message';
}
else
{
    echo 'CAPTHCA is not valid; ignore submission';
}

次の場合、最初の中括弧がありません...

if(isset($_POST['captcha']))
{
    if($_SESSION['captcha'] == $_POST['captcha'])
    {
        //CAPTHCA is valid; proceed the message: save to database, send by e-mail ...
        echo 'CAPTHCA is valid; proceed the message';
    }
    else
    {
        echo 'CAPTHCA is not valid; ignore submission';
    }
}
// Need another else for first if here or keep it closed if you don't have an else
