What are some common mistakes made by beginners when trying to display database entries in a table using PHP?

One common mistake made by beginners when trying to display database entries in a table using PHP is not properly fetching the data from the database and displaying it in the table structure. To solve this, you need to use a loop to iterate over the fetched data and output it within the table rows and cells. 

<?php
// Connect to the database
$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);
}

// Fetch data from the database
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

// Display data in a table
echo "<table>";
echo "<tr><th>ID</th><th>Name</th><th>Email</th></tr>";
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>" . $row["id"] . "</td><td>" . $row["name"] . "</td><td>" . $row["email"] . "</td></tr>";
    }
} else {
    echo "0 results";
}
echo "</table>";

// Close connection
$conn->close();
?>
