What are the potential pitfalls of using date formats in PHP when querying data?

When using date formats in PHP to query data, a potential pitfall is mismatched date formats between the data in the database and the format specified in the query. To avoid this issue, it is important to ensure that the date format used in the query matches the format of the dates stored in the database. 

// Example of querying data with matching date formats
$date = '2022-01-01';
$format_date = date('Y-m-d', strtotime($date));

$query = "SELECT * FROM table WHERE date_column = '$format_date'";
$result = mysqli_query($connection, $query);

// Process the query result
