What are the implications of using inline JavaScript calls like "onmousemove" in PHP code and how can they be improved for better performance?

Using inline JavaScript calls like "onmousemove" in PHP code can lead to mixing presentation and logic, making the code harder to maintain and debug. To improve performance and separation of concerns, it is better to separate the JavaScript behavior from the PHP code by using event listeners in a separate JavaScript file. 

// PHP code
echo '<div id="myElement">Hover over me</div>';
```

```javascript
// JavaScript file
document.getElementById('myElement').addEventListener('mousemove', function() {
    // Your JavaScript logic here
});
