The RecursiveIteratorIterator class in PHP is a useful tool for iterating over the contents of a directory and its subdirectories. One of its methods, getFilename(), returns the filename of the current item being iterated over. Here are some example code snippets that demonstrate the use of this method:

Example 1: Iterate over all files in a directory and print their filenames

$dir = new RecursiveDirectoryIterator('/path/to/directory');
$iter = new RecursiveIteratorIterator($dir);

foreach ($iter as $file) {
    if ($file->isFile()) {
        echo $iter->getFilename() . "\n";
    }
}

In this example, we create a RecursiveDirectoryIterator object to represent the directory we want to iterate over. We then create a RecursiveIteratorIterator object to iterate over the contents of the directory. Inside the loop, we call getFilename() to retrieve the filename of the current item being iterated over. We check if the item is a file using isFile(), and if it is, we print its filename.

Example 2: Filter files by extension and print their filenames

$dir = new RecursiveDirectoryIterator('/path/to/directory');
$filter = new RecursiveCallbackFilterIterator($dir, function($file) {
    return strpos($file->getFilename(), '.txt') !== false;
});
$iter = new RecursiveIteratorIterator($filter);

foreach ($iter as $file) {
    if ($file->isFile()) {
        echo $iter->getFilename() . "\n";
    }
}

In this example, we use a RecursiveCallbackFilterIterator to filter the files being iterated over by extension. Specifically, we only want to include files with a .txt extension. We check the extension using strpos() and then create a new RecursiveIteratorIterator to iterate over the filtered files. Inside the loop, we call getFilename() as before to retrieve the filename of each file. Package/library: The RecursiveIteratorIterator class is part of the PHP Standard Library and does not require any external packages or libraries.
