What are the advantages and disadvantages of using JavaScript to toggle values on the client side in PHP applications?

When toggling values on the client side in PHP applications using JavaScript, the advantage is that it provides a seamless user experience without the need to reload the page. This can improve the overall performance and responsiveness of the application. However, the disadvantage is that it relies on client-side scripting, which may not be secure and could potentially be manipulated by users.

```php
<?php
// PHP code to toggle values using JavaScript
echo '<button onclick="toggleValue()">Toggle Value</button>';
echo '<p id="value">Initial Value</p>';
echo '<script>
function toggleValue() {
  var value = document.getElementById("value").innerHTML;
  if(value === "Initial Value") {
    document.getElementById("value").innerHTML = "Toggled Value";
  } else {
    document.getElementById("value").innerHTML = "Initial Value";
  }
}
</script>';
?>
