How can you limit the display of data from a database table in PHP?

To limit the display of data from a database table in PHP, you can use the SQL query clause "LIMIT" to specify the number of rows to retrieve. This is useful when you have a large dataset and only want to display a certain number of records at a time. By using the LIMIT clause in your SQL query, you can control the amount of data that is fetched from the database and displayed on your webpage. 

// Connect to 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 select data with limit
$sql = "SELECT * FROM myTable LIMIT 10"; // Limiting to 10 rows

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

// Display data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
