In PHP, what steps should be taken to translate a logical algorithm into functional code for grouping and displaying data from a database?

When translating a logical algorithm into functional code for grouping and displaying data from a database in PHP, you should first establish a connection to the database, retrieve the data using SQL queries, group the data as needed, and then display it in the desired format. This can be achieved by using PHP's PDO or mysqli extension to interact with the database and loop through the fetched data to group and display it accordingly. 

<?php

// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

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

if ($result->num_rows > 0) {
    // Group and display the data
    while($row = $result->fetch_assoc()) {
        // Group data as needed
        // Display data in desired format
        echo "ID: " . $row["id"] . " - Name: " . $row["name"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();

?>
