How can the issue of displaying duplicate entries for suppliers in a PHP table be resolved?

Issue: The problem of displaying duplicate entries for suppliers in a PHP table can be resolved by using the DISTINCT keyword in the SQL query to retrieve unique supplier records. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// SQL query to retrieve unique supplier records
$sql = "SELECT DISTINCT supplier_name, supplier_address FROM suppliers";

$result = $conn->query($sql);

// Display the unique supplier records in a table
if ($result->num_rows > 0) {
    echo "<table><tr><th>Supplier Name</th><th>Supplier Address</th></tr>";
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>".$row["supplier_name"]."</td><td>".$row["supplier_address"]."</td></tr>";
    }
    echo "</table>";
} else {
    echo "0 results";
}

$conn->close();
?>
