What are some common practices or resources for detecting Flash plugin in web development, considering the longevity of the topic?

Detecting the Flash plugin in web development is important for providing fallback content or alternative experiences for users who do not have Flash installed or enabled in their browsers. One common practice is to use JavaScript to detect the presence of the Flash plugin by checking the navigator.plugins array or the navigator.mimeTypes array. Another approach is to use server-side detection with PHP to check the User-Agent header for Flash-specific strings. 

<?php
function detectFlashPlugin() {
    $userAgent = $_SERVER['HTTP_USER_AGENT'];
    
    if (strpos($userAgent, 'Shockwave Flash') !== false) {
        return true;
    } else {
        return false;
    }
}

if (detectFlashPlugin()) {
    echo 'Flash plugin detected';
} else {
    echo 'Flash plugin not detected';
}
?>
