How can the code be optimized to improve the efficiency and readability of the MySQL queries in PHP?

To optimize the code for efficiency and readability in MySQL queries in PHP, you can use prepared statements to prevent SQL injection attacks and improve performance by reusing query execution plans. Additionally, you can break down complex queries into smaller, more manageable chunks for better readability. 

// Optimized PHP code using prepared statements for MySQL queries

// Create a connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare a SQL query using a prepared statement
$stmt = $mysqli->prepare("SELECT * FROM users WHERE id = ?");
$id = 1;
$stmt->bind_param("i", $id);
$stmt->execute();

// Get the result set
$result = $stmt->get_result();

// Fetch data from the result set
while ($row = $result->fetch_assoc()) {
    echo "Name: " . $row['name'] . "<br>";
}

// Close the prepared statement and connection
$stmt->close();
$mysqli->close();
