What are the limitations of using PHP for client-side interactive elements like mouseover effects?

PHP is a server-side language, meaning it runs on the server before sending the final HTML to the client's browser. This makes it difficult to create client-side interactive elements like mouseover effects using PHP alone. To achieve this functionality, you would typically use a combination of PHP for server-side processing and JavaScript for client-side interactions. 

// Example of combining PHP and JavaScript for mouseover effect
<?php
// PHP code here for server-side processing

// JavaScript code for client-side mouseover effect
echo '<script>
        function mouseOver() {
            document.getElementById("element").style.color = "red";
        }

        function mouseOut() {
            document.getElementById("element").style.color = "black";
        }
      </script>';
?>

<!-- HTML element with mouseover effect -->
<div id="element" onmouseover="mouseOver()" onmouseout="mouseOut()">Hover over me</div>
