PHP retrieve records from database

I am new to PHP and web development in general. I wrote a simple PHP script based on my knowledge so far. Here it what it looks like, along with the HTML:

<!DOCTYPE HTML>
<html>
    <title>Retrieve Users</title>
    <meta charset="utf-8">
    <body>
        <p> List of Subscribers </p>
        <?php
            $query = "select * from subscribers";
            $con = mysqli_connect("localhost","root","","subscribers");
            $result;
            if(mysqli_connect_errno()){
                header("Location: unavailable.html");
                exit;
            }else{
                $result = mysqli_query($con,$query);
            }
        ?>
        <table>
            <?php 
                global $result;
                while( $row = mysqli_fetch_array($result) ){
                    $email = $row['email'];
                    echo "<tr>";
                    echo "<td>"  $email  "</td>";
                    echo "</tr>";
                }
            ?>
        </table>
    </body>
</html>  

However, I get this in my webpage :

List of Subscribers

"; echo ""; echo ""; } ?>
" $email "  

What changes do I need to make here?

You forgot to concate

echo "<td>".$email."</td>";

UPDATE

The concate was not alone the issue, the file name was having wrong extension.

This kind of situation may happen in following cases

  1. No PHP installed, in this it is most likely you may get php file getting downloaded intead of executing.
  2. Wrong file extension
  3. Using php short tag <? where in php.ini its not enable
