How can PHP developers ensure that dates passed to MySQL queries are in the correct format to avoid unexpected behavior?

When passing dates to MySQL queries in PHP, it's important to ensure that the dates are in the correct format to avoid unexpected behavior. One way to do this is by using PHP's date() function to format the date string before passing it to the query. This ensures that the date is in the expected format for MySQL to process correctly. 

// Example code snippet to ensure dates are in the correct format for MySQL queries
$date = "2022-01-31"; // Date to be passed to MySQL query

// Format the date using PHP's date() function
$formatted_date = date("Y-m-d", strtotime($date));

// Use the formatted date in the MySQL query
$query = "SELECT * FROM table WHERE date_column = '$formatted_date'";
