How can the code on line 12 be improved to avoid errors in PHP form display?

The code on line 12 can be improved by checking if the variable `$_POST['name']` is set before trying to display it. This will prevent PHP errors when the form is first loaded and no data has been submitted yet. By using the `isset()` function, we can ensure that the variable exists before trying to display it. 

<?php
$name = isset($_POST['name']) ? $_POST['name'] : '';
echo '<input type="text" name="name" value="' . $name . '">';
?>
