What are some potential pitfalls of using Flash in web development, especially with the rise of mobile devices?

Potential pitfalls of using Flash in web development include compatibility issues with mobile devices, slower loading times, security vulnerabilities, and the fact that Flash is not supported on many modern browsers. To solve this issue, developers should consider using HTML5, CSS, and JavaScript for animations and interactive elements instead of relying on Flash. 

// Example PHP code using HTML5, CSS, and JavaScript instead of Flash
<!DOCTYPE html>
<html>
<head>
    <title>HTML5 Animation Example</title>
    <style>
        #animation {
            width: 100px;
            height: 100px;
            background-color: red;
            position: relative;
            animation: move 2s infinite;
        }

        @keyframes move {
            0% {left: 0;}
            50% {left: 50%;}
            100% {left: 0;}
        }
    </style>
</head>
<body>
    <div id="animation"></div>
</body>
</html>
