In what scenarios would it be beneficial to create a recursive function to handle directory structures when using the "glob" function in PHP?

When dealing with directory structures using the "glob" function in PHP, it may be beneficial to create a recursive function to handle nested directories. This is useful when you need to search through multiple levels of directories to find specific files or perform operations on files within those directories. By creating a recursive function, you can easily navigate through the directory structure and process files efficiently. 

function recursiveGlob($pattern, $flags = 0) {
    $files = glob($pattern, $flags);
    
    foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
        $files = array_merge($files, recursiveGlob($dir.'/'.basename($pattern), $flags));
    }
    
    return $files;
}

$files = recursiveGlob('path/to/directory/*.txt');
foreach ($files as $file) {
    echo $file . "\n";
}
