Are there any potential pitfalls or limitations when using platform-dependent methods to detect Flash plugin in PHP?

When using platform-dependent methods to detect the Flash plugin in PHP, one potential pitfall is that the method may not be reliable across different operating systems or browser configurations. To address this limitation, it is recommended to use a more universal method that can accurately detect the Flash plugin regardless of the platform.

// Check if Flash plugin is installed using a more universal method
function isFlashInstalled() {
    return (bool) strpos($_SERVER['HTTP_USER_AGENT'], 'Shockwave Flash');
}

// Example usage
if (isFlashInstalled()) {
    echo "Flash plugin is installed.";
} else {
    echo "Flash plugin is not installed.";
}
