What are some best practices for selecting data from an SQL database based on date criteria using PHP?

When selecting data from an SQL database based on date criteria using PHP, it is important to properly format the date in the SQL query to ensure accurate results. One common approach is to use the `DATE_FORMAT` function in MySQL to format the date column in the database and compare it with the desired date range. Additionally, using prepared statements can help prevent SQL injection attacks when passing date criteria as parameters in the query. 

// Assuming $start_date and $end_date are the desired date range
$start_date = '2022-01-01';
$end_date = '2022-01-31';

// Establish a database connection
$connection = new mysqli('localhost', 'username', 'password', 'database_name');

// Prepare and execute the SQL query with date criteria
$query = $connection->prepare("SELECT * FROM table_name WHERE DATE_FORMAT(date_column, '%Y-%m-%d') BETWEEN ? AND ?");
$query->bind_param('ss', $start_date, $end_date);
$query->execute();

// Fetch the results
$result = $query->get_result();
while ($row = $result->fetch_assoc()) {
    // Process the data
}

// Close the connection
$connection->close();
