What potential issue is the user facing with displaying the content of a specific column in the database?

The user may be facing an issue with displaying the content of a specific column in the database due to incorrect column name or database connection errors. To solve this issue, the user should ensure that the column name is spelled correctly and that the database connection is established properly. 

<?php
// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Query to select specific column data
$sql = "SELECT column_name FROM table_name";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column Name: " . $row["column_name"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
