What considerations should be taken into account when recursively counting files and directories in PHP?

When recursively counting files and directories in PHP, it is important to consider the efficiency of the code to handle large directory structures. One way to achieve this is by using a recursive function that traverses the directory structure and counts the files and directories. Additionally, error handling should be implemented to handle any potential issues such as permission errors or symbolic links. 

function countFilesAndDirectories($dir) {
    $count = 0;
    $files = glob(rtrim($dir, '/') . '/*');
    
    if ($files !== false) {
        foreach ($files as $file) {
            if (is_file($file)) {
                $count++;
            } elseif (is_dir($file)) {
                $count++;
                $count += countFilesAndDirectories($file);
            }
        }
    }
    
    return $count;
}

$directory = '/path/to/directory';
$count = countFilesAndDirectories($directory);
echo "Total files and directories in $directory: $count";
