Are there best practices for passing additional variables to buttons during their creation in PHP?

When creating buttons dynamically in PHP, you may need to pass additional variables to the button's onclick function. One way to achieve this is by using data attributes to store the extra information and then accessing it within the onclick function. This allows you to pass custom data to the button without cluttering the HTML markup or using global variables. 

<?php
// Additional variable to pass to the button
$customData = "Hello, World!";

// Creating a button with onclick function that accesses the custom data
echo '<button onclick="handleClick(this)" data-custom="' . $customData . '">Click Me</button>';

// JavaScript function to handle the button click and access the custom data
echo '<script>
function handleClick(button) {
    var customData = button.getAttribute("data-custom");
    alert(customData);
}
</script>';
?>
