How can PHP developers optimize their code to ensure better data management and display in iframes within PHP forms?

To optimize code for better data management and display in iframes within PHP forms, developers can utilize AJAX to dynamically load content into the iframe without refreshing the entire page. This can improve user experience by making the form more interactive and responsive. 

// PHP code snippet for dynamically loading content into an iframe using AJAX

<?php
if(isset($_POST['submit'])){
    $data = $_POST['data']; // retrieve form data
    
    // AJAX request to load data into iframe
    echo "<script>";
    echo "document.getElementById('iframe_id').src = 'iframe_content.php?data=' + encodeURIComponent('" . $data . "');";
    echo "</script>";
}
?>

<!-- HTML form with iframe -->
<form method="post" action="">
    <input type="text" name="data">
    <input type="submit" name="submit" value="Submit">
</form>

<iframe id="iframe_id" src=""></iframe>
