What is the process for uploading an entire folder using PHP?

To upload an entire folder using PHP, you can iterate through the files in the folder and upload each file individually. You can use functions like `scandir()` to get a list of files in the folder and then use `move_uploaded_file()` to move each file to the desired location.

$folderPath = 'path/to/folder/';

$files = scandir($folderPath);

foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        $filePath = $folderPath . $file;
        $newLocation = 'path/to/uploaded/files/' . $file;
        if (move_uploaded_file($filePath, $newLocation)) {
            echo 'File ' . $file . ' uploaded successfully.<br>';
        } else {
            echo 'Failed to upload file ' . $file . '.<br>';
        }
    }
}
