在执行PHP脚本时没有在Postman中获取任何结果数据

Question

I have hosted my php file on AWS EC2 instance(runs Ubuntu). My other php files are getting perfectly executed and giving me desired output while the following code produces an error.

ERROR : 500 Internal Server Error and shows hat unexpected end of File

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
   include 'init.php';
    showData();
}

function showData()
{
    global $connect;
    $mandir_Cat_Id = $_POST["mandir_Cat_Id"];

    $stmt = $connect->prepare("SELECT mandir_id,mandir_Name from tblmandirMain WHERE mandir_Category_FK=?");
    $stmt->bind_param("i", $mandir_Cat_Id);
    $stmt->execute();
    $result = $stmt->get_result();
    $stmt->close();

    //$result = mysqli_query($connect, $query);

    if ($result->num_rows === 0) {
        $array["message"] = "Data not found";
        $array["status"] = "404";
    } else {
        while ($row = $result->fetch_assoc()) {
            $array["results"][] = $row;
        }
        $array["message"] = "Data found";
        $array["status"] = "200";

    }

    mysqli_close($connect);
    header('Content-Type:Application/json');
    echo json_encode($array);
}
?>

The code runs perfectly and gives me the following JSON output :

{
"results": [
    {
        "mandir_id": 1,
        "mandir_Name": "Somnath Jyotirlinga"
