Are there any best practices for incorporating HTML code before and after selected text in a textarea using PHP?

When incorporating HTML code before and after selected text in a textarea using PHP, you can achieve this by getting the selected text, adding the HTML code before and after it, and then replacing the original text in the textarea with the modified text. This can be done by using JavaScript to get the selected text and send it to the server-side PHP script for processing. 

<?php
if(isset($_POST['selected_text'])) {
    $selected_text = $_POST['selected_text'];
    $before_text = '<strong>';
    $after_text = '</strong>';
    
    // Add HTML code before and after selected text
    $modified_text = $before_text . $selected_text . $after_text;

    // Replace original text in the textarea with modified text
    echo '<script>document.getElementById("myTextarea").value = document.getElementById("myTextarea").value.replace("' . $selected_text . '", "' . $modified_text . '");</script>';
}
?>
