Are there any best practices for integrating a datepicker script into an existing PHP website?

Issue: When integrating a datepicker script into an existing PHP website, it is important to ensure that the script is properly included in the HTML code and that the necessary PHP code is implemented to handle the selected date. Solution: To integrate a datepicker script into an existing PHP website, you can use a popular library like jQuery UI Datepicker. First, include the necessary CSS and JavaScript files in the HTML head section of your PHP file. Then, add an input field with a specific ID for the datepicker to target. Finally, use JavaScript to initialize the datepicker on the input field.
