What are some common pitfalls when using the input type "date" in HTML forms with PHP for date processing?

When using the input type "date" in HTML forms with PHP for date processing, a common pitfall is that the date format may not be compatible with PHP's date functions. To solve this issue, you can use the strtotime() function in PHP to convert the date string into a Unix timestamp, which can then be used for further processing. 

// Retrieve the date value from the HTML form
$date = $_POST['date'];

// Convert the date string to a Unix timestamp using strtotime()
$timestamp = strtotime($date);

// Use the timestamp for further date processing
$processed_date = date('Y-m-d', $timestamp);

// Output the processed date
echo $processed_date;
