count the number of files in directory & its sub directories

A recursion counts to the number of files in a specific directory.

Code:

// folder path end with '/'
function directoryListCount($folderPath) {
 
   
 
    $num_files= 0;
 
    $dirStream = opendir($folderPath);
 
    if (!$dirStream) return -1;
 
    while ($file = readdir($dirStream)) {
 
        if ($file == '.' || $file == '..') continue;
 
        if (is_dir($folderPath. $file)){      
            $num_files+= directoryListCount($folderPath. $file . DIRECTORY_SEPARATOR);
        }
        else {
            $num_files++;  
        }
    }
 
    closedir($dirStream);
 
    return $num_files;
}
