How can PHP developers effectively utilize database management systems for data sorting and analysis tasks?

To effectively utilize database management systems for data sorting and analysis tasks, PHP developers can use SQL queries to retrieve, filter, and manipulate data stored in databases. By writing efficient queries and utilizing features like joins, indexes, and aggregate functions, developers can perform complex data analysis tasks within their PHP applications. 

// 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);
}

// Example SQL query to retrieve data from a table and sort it
$sql = "SELECT * FROM table_name ORDER BY column_name DESC";
$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();
