What are some best practices for integrating PHP scripts to showcase real-time cart values on a separate webpage?

To showcase real-time cart values on a separate webpage using PHP scripts, you can utilize AJAX to periodically fetch updated cart values from the server without refreshing the entire page. This allows for a seamless and dynamic user experience.

// PHP script to fetch real-time cart values
<?php
// Connect to database or any other data source
// Query to get cart values
$cartValue = 100; // Example cart value
echo $cartValue;
?>
```

```html
<!-- HTML code to display real-time cart values -->
<div id="cartValue"></div>

<script>
// AJAX script to update cart values in real-time
setInterval(function(){
  $.ajax({
    url: 'fetch_cart_values.php',
    success: function(data){
      $('#cartValue').html(data);
    }
  });
}, 1000); // Update every 1 second
</script>
