How can PHP be used to implement a preview feature for user-generated content before saving it?

When implementing a preview feature for user-generated content in PHP, you can create a form where users input their content. Upon submitting the form, the content is displayed in a preview section using PHP before it is saved to the database. This allows users to see how their content will appear before finalizing it.

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $user_content = $_POST['user_content'];
    // Display the user-generated content in a preview section
    echo "<h2>Preview:</h2>";
    echo "<p>" . $user_content . "</p>";
}
?>

<form method="post" action="">
    <label for="user_content">Enter your content:</label><br>
    <textarea name="user_content" rows="4" cols="50"></textarea><br>
    <input type="submit" value="Preview">
</form>
