What are the potential pitfalls of using different date formats in PHP and MySQL when comparing dates?

When comparing dates between PHP and MySQL, using different date formats can lead to inaccurate results or errors. To avoid this issue, it is important to ensure that dates are stored and compared in a consistent format, such as YYYY-MM-DD. 

// Convert PHP date to MySQL format before comparing
$phpDate = '2021-10-15';
$mysqlDate = date('Y-m-d', strtotime($phpDate));

// Compare dates in MySQL query
$query = "SELECT * FROM table WHERE date_column = '$mysqlDate'";
$result = mysqli_query($connection, $query);
