Are there any specific PHP functions or techniques that can help optimize the retrieval and display of data from a MySQL database?

To optimize the retrieval and display of data from a MySQL database in PHP, you can use techniques such as using prepared statements to prevent SQL injection, fetching only the necessary data using SELECT queries with specific columns, and caching frequently accessed data to reduce database queries. 

// Example of using prepared statements to retrieve data from a MySQL database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$stmt = $pdo->prepare("SELECT column1, column2 FROM mytable WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
