Is using a Java applet a recommended solution for uploading multiple files with PHP?

Using a Java applet for uploading multiple files with PHP is not a recommended solution due to security concerns and the decreasing support for Java applets in modern browsers. Instead, a better approach would be to use HTML5 file input fields with the multiple attribute to allow users to select and upload multiple files at once.

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="files[]" multiple>
    <input type="submit" value="Upload Files">
</form>
