What is the recommended approach for calling a function in a button click event in PHP?

When calling a function in a button click event in PHP, the recommended approach is to use JavaScript to handle the button click event and make an AJAX request to a PHP script that will execute the desired function. This allows for a seamless user experience without having to reload the entire page. 

<button id="myButton">Click Me</button>

<script>
document.getElementById("myButton").addEventListener("click", function() {
  var xhr = new XMLHttpRequest();
  xhr.open("GET", "my_php_script.php", true);
  xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && xhr.status == 200) {
      console.log(xhr.responseText);
    }
  };
  xhr.send();
});
</script>
