What are some potential pitfalls when using multiple date comparisons in a PHP MySQL query?

When using multiple date comparisons in a PHP MySQL query, one potential pitfall is not properly formatting the dates in the query. To avoid this issue, it is important to format the dates using the DATE() function in MySQL to ensure they are compared correctly. Additionally, be mindful of the date format being used in PHP and MySQL to avoid any discrepancies. 

// Example of using multiple date comparisons in a PHP MySQL query with proper date formatting

// Assuming $start_date and $end_date are properly formatted dates in PHP

// Format the dates for MySQL comparison
$start_date_mysql = date('Y-m-d', strtotime($start_date));
$end_date_mysql = date('Y-m-d', strtotime($end_date));

// Construct the MySQL query with date comparisons
$query = "SELECT * FROM table_name WHERE date_column BETWEEN '$start_date_mysql' AND '$end_date_mysql'";

// Execute the query using mysqli_query() or PDO
$result = mysqli_query($connection, $query);

// Process the result set as needed
