Is it necessary to have a basic understanding of JavaScript in order to implement a plus/minus toggle feature in PHP?

To implement a plus/minus toggle feature in PHP without using JavaScript, you can achieve this by utilizing PHP to handle the toggling functionality. You can store the current state (plus or minus) in a session variable and update it accordingly when the toggle is clicked. By checking the session variable, you can dynamically display the appropriate content based on the toggle state. 

<?php
session_start();

// Initialize toggle state if not set
if (!isset($_SESSION['toggle_state'])) {
    $_SESSION['toggle_state'] = 'plus';
}

// Handle toggle action
if (isset($_GET['toggle'])) {
    if ($_SESSION['toggle_state'] == 'plus') {
        $_SESSION['toggle_state'] = 'minus';
    } else {
        $_SESSION['toggle_state'] = 'plus';
    }
}

// Display content based on toggle state
if ($_SESSION['toggle_state'] == 'plus') {
    echo "Content when toggle is plus";
} else {
    echo "Content when toggle is minus";
}

// Toggle link
echo '<a href="?toggle">Toggle</a>';
?>
