How can the issue of form submission when pressing the Return key in a text field be addressed in PHP?

Issue: When a user presses the Return key in a text field, the form is submitted prematurely without the user intending to do so. This can be addressed by preventing the form submission when the Return key is pressed in the text field using JavaScript. 

<?php
// PHP code to handle form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
}
?>

<form method="post" action="">
    <input type="text" name="textfield" onkeydown="return event.key != 'Enter';">
    <input type="submit" value="Submit">
</form>
