Number of lines of files in a folder and recursive

To make a estimation price of IonCube online encryption I had to count the number of lines of my php files inside a specific folder and respective subfolders.

<?php
class Line_Counter
{
    private $filepath;
    private $files = array();

    public function __construct($filepath)
    {
        $this->filepath = $filepath;
    }

    public function countLines($extensions = array('php'))
    {
        $it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($this->filepath));
        foreach ($it as $file)
        {
           // if ($file->isDir() || $file->isDot())
           if ($file->isDir() )
            {
                continue;
            }
            $parts = explode('.', $file->getFilename());
            $extension = end($parts);
            if (in_array($extension, $extensions))
            {
                $files[$file->getPathname()] = count(file($file->getPathname()));
            }
        }
        return $files;
    }

    public function showLines()
    {
        echo '<pre>';
        print_r($this->countLines());
        echo '</pre>';
    }

    public function totalLines()
    {
        return array_sum($this->countLines());
    }

}

// Get all files with line count for each into an array
$loc = new Line_Counter('.');
$loc->showLines();

echo '<br><br> Total Lines of code: ';
echo $loc->totalLines();

?>
