How can different panels be displayed based on selection from a combobox in PHP?

To display different panels based on selection from a combobox in PHP, you can use JavaScript to show/hide the panels dynamically. When the combobox selection changes, you can trigger a JavaScript function to hide all panels and then show the selected panel based on the selected value. 

<?php
// PHP code to handle form submission
if(isset($_POST['submit'])){
    $selected_option = $_POST['options'];
    // Handle selected option
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Display Panels based on Selection</title>
    <script>
        function showPanel(panelId) {
            var panels = document.getElementsByClassName('panel');
            for (var i = 0; i < panels.length; i++) {
                panels[i].style.display = 'none';
            }
            document.getElementById(panelId).style.display = 'block';
        }
    </script>
</head>
<body>
    <form method="post">
        <select name="options" onchange="showPanel(this.value)">
            <option value="panel1">Panel 1</option>
            <option value="panel2">Panel 2</option>
            <option value="panel3">Panel 3</option>
        </select>
        <br><br>
        <div id="panel1" class="panel" style="display:none;">Panel 1 Content</div>
        <div id="panel2" class="panel" style="display:none;">Panel 2 Content</div>
        <div id="panel3" class="panel" style="display:none;">Panel 3 Content</div>
        <br>
        <input type="submit" name="submit" value="Submit">
    </form>
</body>
