How can PHP beginners ensure proper output of HTML text after a button click event?

PHP beginners can ensure proper output of HTML text after a button click event by using a form with a submit button and checking if the form has been submitted. If the form has been submitted, the PHP code can process the input and generate the desired HTML output. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data and generate HTML output
    $input = $_POST["input"];
    echo "<p>You entered: $input</p>";
}
?>

<form method="post">
    <input type="text" name="input">
    <button type="submit">Submit</button>
</form>
