What are the best practices for comparing dates in MySQL queries in PHP to avoid errors or unexpected results?

When comparing dates in MySQL queries in PHP, it is important to use the correct date format to avoid errors or unexpected results. One common mistake is comparing dates as strings, which can lead to incorrect comparisons. To ensure accurate date comparisons, it is recommended to use the DATE_FORMAT function in MySQL to format dates consistently before comparing them. 

// Example of comparing dates in MySQL queries in PHP using DATE_FORMAT function
$date = '2022-01-01'; // Date to compare
$formattedDate = date('Y-m-d', strtotime($date)); // Format date using PHP
$query = "SELECT * FROM table_name WHERE DATE_FORMAT(date_column, '%Y-%m-%d') = '$formattedDate'";
// Execute the query and fetch results
