How can delays in database queries impact the display of data on a PHP webpage?

Delays in database queries can impact the display of data on a PHP webpage by causing slow loading times or errors in retrieving and rendering the data. To mitigate this issue, you can optimize your database queries by indexing columns used in WHERE clauses, limiting the amount of data retrieved, and caching query results where possible. 

// Example of optimizing database query to reduce delays
$query = "SELECT * FROM table_name WHERE column_name = :value LIMIT 10";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':value', $value, PDO::PARAM_STR);
$stmt->execute();
$results = $stmt->fetchAll();
