How can PHP be used to prevent premature form submission when pressing Enter in an input field?

When a user presses Enter in an input field within a form, it can lead to premature form submission before the user has completed filling out all required fields. To prevent this, you can use JavaScript to capture the Enter key press event and stop the form submission. Here is a simple PHP code snippet that includes the necessary JavaScript function to prevent premature form submission: 

<?php
// PHP code here to process form submission

?>

<!DOCTYPE html>
<html>
<head>
    <title>Prevent Premature Form Submission</title>
</head>
<body>

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

</body>
</html>
