How can PHP be utilized to efficiently handle key-value pairs from a MySQL database for CSS generation?

To efficiently handle key-value pairs from a MySQL database for CSS generation, you can use PHP to fetch the data from the database and then dynamically generate CSS styles based on the retrieved key-value pairs. This can be achieved by looping through the data and outputting CSS rules accordingly. 

<?php
// Connect to MySQL 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 key-value pairs from database
$sql = "SELECT * FROM css_styles";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output CSS rules based on key-value pairs
    echo "<style>";
    while($row = $result->fetch_assoc()) {
        echo "." . $row["class"] . " { " . $row["property"] . ": " . $row["value"] . "; }";
    }
    echo "</style>";
} else {
    echo "0 results";
}

$conn->close();
?>
