Trying to show data from mysql db to my page!!

$servername = "sql303.byethost6.com";
$username = "b6_17546085";
$password = "hiding password but this works";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully<br>";
?>
<?php
$sql = "SELECT id, thePost FROM postings";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["thePost"]. "<br>";
    }
} else {
    echo "0 results";
}
$conn->close();
