What are some potential pitfalls of relying on JavaScript for date selection in PHP forms?

Potential pitfalls of relying on JavaScript for date selection in PHP forms include the risk of users disabling JavaScript and submitting incorrect date formats. To mitigate this issue, server-side validation of the date input should be implemented in PHP to ensure the date format is correct before processing the form data. 

// Server-side validation for date input in PHP form
$date = $_POST['date'];

if (DateTime::createFromFormat('Y-m-d', $date) === false) {
    $errors[] = "Invalid date format. Please enter a date in the format YYYY-MM-DD.";
}
