How can PHP developers ensure accurate data retrieval and manipulation when dealing with datetime values in database queries?

When dealing with datetime values in database queries, PHP developers can ensure accurate data retrieval and manipulation by using prepared statements with parameterized queries. This helps prevent SQL injection attacks and ensures that datetime values are properly formatted and interpreted by the database. 

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM mytable WHERE created_at >= :start_date AND created_at <= :end_date");

// Bind the datetime values to the parameters
$start_date = '2022-01-01 00:00:00';
$end_date = '2022-01-31 23:59:59';
$stmt->bindParam(':start_date', $start_date);
$stmt->bindParam(':end_date', $end_date);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Loop through the results and do something with them
foreach ($results as $row) {
    // Do something with the data
}
