What are some potential pitfalls when comparing dates in PHP and MySQL?

When comparing dates in PHP and MySQL, one potential pitfall is the difference in date formats between the two systems. To avoid issues, it's important to ensure that dates are formatted consistently before comparing them. One way to do this is by using the DATE_FORMAT function in MySQL to format dates in a standard format that can be easily compared with PHP. 

// Example code to compare dates in PHP and MySQL

// Assuming $phpDate is a PHP date object and $mysqlDate is a date retrieved from MySQL
$phpFormattedDate = $phpDate->format('Y-m-d'); // Format PHP date as 'YYYY-MM-DD'
$query = "SELECT * FROM table_name WHERE DATE_FORMAT(mysql_date_column, '%Y-%m-%d') = '$phpFormattedDate'";
// Execute the query and compare dates
