What are the limitations of using PHP for real-time character counting in a text area?

When using PHP for real-time character counting in a text area, the limitation is that PHP is a server-side language and does not have the capability to interact with the user interface in real-time. To overcome this limitation, you can use JavaScript to handle the real-time character counting on the client-side. 

// PHP code for real-time character counting in a text area
