What is the limitation of PHP in directly calling a function through a button click?

PHP is a server-side language, which means it cannot directly call a function in response to a button click on the client-side (browser). To achieve this functionality, you can use AJAX (Asynchronous JavaScript and XML) to send a request to the server when the button is clicked, triggering the PHP function execution. 

<?php
if(isset($_POST['button_click'])) {
    // Call your PHP function here
    your_function_name();
}

function your_function_name() {
    // Your function logic here
}

?>

<form method="post">
    <button type="submit" name="button_click">Click me</button>
</form>
