Is there a best practice for handling form submission with the "Enter" key in PHP?

When a form is submitted using the "Enter" key, it can sometimes result in unexpected behavior such as submitting the form multiple times or not submitting at all. To handle form submission with the "Enter" key in PHP, you can use JavaScript to prevent the default form submission action and instead trigger a manual form submission using AJAX. 

```php
<script>
    document.addEventListener('keydown', function(event) {
        if (event.key === 'Enter') {
            event.preventDefault();
            document.getElementById('myForm').submit();
        }
    });
</script>
```

In this code snippet, the JavaScript event listener is added to the document to listen for the "Enter" key press. When the "Enter" key is pressed, the default form submission action is prevented using `event.preventDefault()`, and then the form with the id `myForm` is submitted manually using `document.getElementById('myForm').submit()`. This allows for more control over how form submissions are handled when the "Enter" key is pressed.
