What are the potential pitfalls of mixing PHP and JavaScript for displaying the current date in an input field?

Mixing PHP and JavaScript for displaying the current date in an input field can lead to synchronization issues between server-side and client-side time. To solve this problem, you can use PHP to initially set the date value in the input field and then use JavaScript to update it dynamically on the client-side. 

<input type="text" id="dateInput" value="<?php echo date('Y-m-d'); ?>">
<script>
    document.getElementById('dateInput').addEventListener('focus', function() {
        var currentDate = new Date().toISOString().split('T')[0];
        document.getElementById('dateInput').value = currentDate;
    });
</script>
