How can PHP be used to handle form submission without the need for a submit button?

To handle form submission without the need for a submit button, you can use JavaScript to automatically submit the form when the user finishes entering data. This can be achieved by listening for changes in form inputs and triggering form submission programmatically. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  // Handle form data here
  $name = $_POST['name'];
  $email = $_POST['email'];
  
  // Process the form data as needed
}
?>

<form method="post" id="myForm">
  <input type="text" name="name" placeholder="Name">
  <input type="email" name="email" placeholder="Email">
</form>

<script>
document.addEventListener('input', function (event) {
  if (event.target.closest('form')) {
    document.getElementById('myForm').submit();
  }
});
</script>
