Solution in PHP (judge verdict: Accepted)

<?php

while (true) {
    fscanf(STDIN, '%d %d', $height, $width);
    if ($height == 0 && $width == 0) break;
    
    $rentangle = new Rectangle($height, $width);
    Drawer::drawObject($rentangle);
    
}

class Rectangle
{
    private $height;
    private $width;
    private $char = '#';
    
    public function __construct($height, $width)
    {
        $this->height = $height;
        $this->width  = $width;
    }
    
    public function draw()
    {
        for ($i = 0; $i < $this->height; $i++) {
            $this->drawLine($this->width, $this->char);
        }
    }
    
    public function drawLine()
    {
        echo str_repeat($this->char, $this->width), PHP_EOL;
    }
}

class Drawer
{
    public static function drawObject($object)
    {
        $object->draw();
        Self::drawEmptyLine();
    }
    
    public static function drawEmptyLine()
    {
        echo PHP_EOL;
