What are some common pitfalls to avoid when trying to display a loading animation while PHP scripts are processing data?

One common pitfall to avoid when displaying a loading animation while PHP scripts are processing data is not properly handling the AJAX request and response. To solve this issue, you can use JavaScript to make an AJAX request to the PHP script, display the loading animation, and then hide it once the script has finished processing. 

<?php
// Your PHP script that processes data
// For demonstration purposes, let's say this script takes some time to process data
sleep(5);

// Return a JSON response
echo json_encode(['status' => 'success']);
?>
```

            $.ajax({
                url: 'process_data.php',
                type: 'GET',
                success: function(response) {
                    $('#loading').hide();
                    console.log('Data processed successfully');
                },
                error: function() {
                    $('#loading').hide();
                    console.log('Error processing data');
                }
