How can SQL queries be optimized when dealing with "datetime" fields in PHP?

When dealing with "datetime" fields in SQL queries in PHP, it is important to properly format the datetime values to match the database format. This can be achieved by using PHP's date() function to convert datetime values to the correct format before including them in the SQL query. Additionally, using prepared statements can help prevent SQL injection attacks and improve query performance. 

// Example code snippet for optimizing SQL queries with datetime fields in PHP
$datetime = date('Y-m-d H:i:s', strtotime('2022-01-01 12:00:00'));

// Using prepared statements to execute the SQL query
$stmt = $pdo->prepare("SELECT * FROM table WHERE datetime_column = :datetime");
$stmt->bindParam(':datetime', $datetime);
$stmt->execute();

// Fetching results
$results = $stmt->fetchAll();
