How can the "onKeyDown" attribute be used to submit a form in PHP?

To submit a form in PHP using the "onKeyDown" attribute, you can create a hidden submit button and trigger its click event when a specific key is pressed. This can be achieved by using JavaScript to listen for the keydown event and then programmatically clicking the hidden submit button when the desired key is pressed. 

<form id="myForm" action="submit.php" method="post">
  <input type="text" name="inputField" onKeyDown="submitForm(event)">
  <input type="submit" id="hiddenSubmitButton" style="display:none">
</form>

<script>
function submitForm(event) {
  if (event.keyCode === 13) { // Check if Enter key is pressed
    document.getElementById('hiddenSubmitButton').click(); // Click the hidden submit button
  }
}
</script>
