What are the advantages and disadvantages of using JavaScript to solve the player on/off button issue instead of PHP?

The issue is creating a player on/off button for a website. One way to solve this is by using JavaScript to toggle the player's state when the button is clicked. JavaScript can be used to dynamically update the player's status without the need to reload the page, providing a smoother user experience.

<?php
// PHP code snippet to implement player on/off button
$playerStatus = "off";

if(isset($_POST['toggle'])){
    if($playerStatus == "off"){
        $playerStatus = "on";
    } else {
        $playerStatus = "off";
    }
}

echo "<form method='post'>";
echo "<input type='submit' name='toggle' value='Toggle Player'>";
echo "</form>";

echo "Player is currently: " . $playerStatus;
?>
