How can HTML and PHP code be optimized to prevent the default value from being overwritten during form updates?

To prevent the default value from being overwritten during form updates, you can check if the form has been submitted and only update the value if a new value has been provided. This can be done by using the ternary operator to set the value based on whether the form has been submitted or not. 

<?php
$default_value = "Default Value";
$new_value = isset($_POST['input_field']) ? $_POST['input_field'] : $default_value;
?>
<input type="text" name="input_field" value="<?php echo $new_value; ?>">
