What are some common pitfalls to avoid when integrating JavaScript frameworks like jQuery into PHP projects?

One common pitfall to avoid when integrating JavaScript frameworks like jQuery into PHP projects is not properly handling the interaction between server-side PHP code and client-side JavaScript code. To ensure smooth communication between the two, it is important to use AJAX requests to send data between the server and client without refreshing the page. 

// PHP code to handle AJAX request
if(isset($_POST['data'])){
    $data = $_POST['data'];
    
    // Process data on the server side
    
    // Send response back to client
    echo json_encode(['success' => true, 'message' => 'Data processed successfully']);
    exit;
}
```

```javascript
// JavaScript code to send AJAX request
$.ajax({
    url: 'process_data.php',
    type: 'POST',
    data: {data: 'example_data'},
    success: function(response){
        console.log(response);
    },
    error: function(xhr, status, error){
        console.log('Error: ' + error);
    }
});
