How can PHP variables be passed through a link activated by a button?

To pass PHP variables through a link activated by a button, you can use a combination of HTML form with hidden input fields and JavaScript to submit the form when the button is clicked. This way, the PHP variables can be sent as form data to another PHP script or page. 

<form id="myForm" action="process.php" method="post">
    <input type="hidden" name="variable1" value="<?php echo $variable1; ?>">
    <input type="hidden" name="variable2" value="<?php echo $variable2; ?>">
    <button type="submit" onclick="document.getElementById('myForm').submit();">Submit</button>
</form>
