MySQLi Select to PHP variable

Question

I wrote a PHP script with a database connection, which appears to work properly. The problem I'm having is in using a SELECT statement to fetch values from my database and assign those values to PHP variables.

This is my table:

If I copy the SQL into PHPMyAdmin, I get the right result, so I trust the query itself.

I get an error, if I write:

echo $result;

What do I do wrong?

This is my full code:

<?php
$servername = "XXXXXX";
$username = "XXXXXX";
$password = "XXXXX";
$dbname = "XXXXXX";


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

$test_code = $_GET['code'];
$product_name = $_GET['product'];


// sql to create table
$sql = "CREATE TABLE IF NOT EXISTS code_ever (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
produkt VARCHAR(50) NOT NULL,
code VARCHAR(30) NOT NULL
)";

if ($conn->query($sql) === TRUE) {

} else {

}

// sql to create table
$sql = "CREATE TABLE IF NOT EXISTS code_scanned (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
produkt VARCHAR(50) NOT NULL,
code VARCHAR(30) NOT NULL
)";

if ($conn->query($sql) === TRUE) {

} else {

}

$query  = "SELECT code FROM code_ever WHERE code = 'XKBKNABJK'";
$result = mysqli_query($conn, $query);

if($result)
{

echo $result;

} 
else
{

echo("Sorry:".mysqli_error($conn));

}

$conn->close();
?>

You need to fetch the results.

$query = "SELECT code FROM code_ever WHERE code = 'XKBKNABJK'";

    if ($result = mysqli_query($conn, $query)) {

        /* fetch associative array */
        while ($row = mysqli_fetch_assoc($result)) {
            echo $row["code"];
        }

        /* free result set */
        mysqli_free_result($result);
    }

Aside from fetching the results you should redesign the table. You shouldn't have more than one value per 'table cell'. For instance you have comma separated values for the size/color etc of the product. You should have those as separate attributes in the table or maybe even a separate table.

Example:

Without fetching record you cant print the result

Use

$result = mysqli_query($con, $query);
While ( $final =   mysqli_fetch_array ($result)){
echo $final['code'];
}
