In PHP, how can developers ensure that a query only returns the 10 newest entries from a database table for further processing?

To ensure that a query only returns the 10 newest entries from a database table, developers can use the ORDER BY clause in conjunction with the LIMIT clause in their SQL query. By sorting the entries in descending order based on a timestamp or an auto-incrementing ID, and then limiting the result set to 10 rows, only the newest entries will be returned for further processing. 

<?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);
}

// Query to select the 10 newest entries from a table
$sql = "SELECT * FROM table_name ORDER BY timestamp_column DESC LIMIT 10";
$result = $conn->query($sql);

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

$conn->close();
?>
