解析错误：语法错误，文件意外结束...第43行

Question

在标题中，我收到此错误，我的代码如下：

    require_once('../connect.php');

$id = $_GET["id"];
if(!empty($id)) {

$sql = "SELECT FROM predictions WHERE id=".$id;

if ($result->num_rows > 0) {

while($row = $result->fetch_assoc()) {

    echo '
    <form action="edit2.php" method="POST">
        Teams:<br />
        <input type="text" name="teams" value="'.$row["teams"].'" required><br />
        Date:<br />
        <input type="text" name="date" value="'.$row["date_match"].'" required><br />
        Prediction:<br />
        <input type="text" name="prediction" value="'.$row["prediction"].'" required><br />
        Risk:<br />
        <input type="text" name="risk" value="'.$row["risk"].'" required><br />
        <input type="submit" name="submit" class="btn" value="edit">
    </form>
    ';
}
} else {
    echo "0 results";
}

if(isset($_POST["submit"])) {
    $sql = "INSERT INTO predictions (teams, date_match, prediction, risk) VALUES ('".$_POST["teams"]."', '".$_POST["date"]."', '".$_POST["prediction"]."', '".$_POST["risk"]."',)";

    if ($conn->query($sql) === TRUE) {
        header("location: ../../index.php");
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

$conn->close();

这里有什么问题？ .................................................. .................................................. ...............
