php unable to select data

Question

I'm trying to select a SINGLE value from the mysql database. I have run the query in phpmyadmin and it work great. But when I echo the $result, I get nothing... by the way,for the database and password I use xxx because I don't want to show it... My insert query works very well

Thanks

<?php

//Create Connection
$servername = "localhost";
$username = "root";
$password = "xxx";
$dbname = "xxx";



//Connect
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT StartPriceUnder FROM YJ_Value";
$result = $conn->query($sql);



echo hi;
echo $result;
echo ya;

$conn->close();

?>

Try this:

<?php
$servername = "localhost";
$username = "root";
$password = "xxx";
$dbname = "xxx";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT StartPriceUnder FROM YJ_Value";
$result = $conn->query($sql);

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