How can PHP be used to allow users to format text without HTML knowledge?

To allow users to format text without HTML knowledge, you can create a simple text editor using PHP that provides buttons for common formatting options such as bold, italic, underline, and bullet points. This editor can then convert the user's input into HTML tags before displaying it on the webpage. 

<?php
if(isset($_POST['submit'])){
    $formatted_text = $_POST['text'];
    $formatted_text = nl2br($formatted_text); // Convert new lines to <br> tags
    $formatted_text = htmlspecialchars($formatted_text); // Convert special characters to HTML entities
    echo $formatted_text;
}
?>

<form method="post">
    <textarea name="text" rows="10" cols="50"></textarea><br>
    <input type="submit" name="submit" value="Format Text">
</form>
