Solution in PHP (judge verdict: Accepted)

<?php
    while(true){
        list($height, $width) = explode(" ",trim(fgets(STDIN)));

        if($height == 0 && $width == 0) exit;
    
        $bar = "";
        for($i = 0; $i < $width; $i++){
            $bar .= "#";
        }
    
        for($j = 0; $j < $height; $j++){
            print $bar."\n";
        }

        print "\n";
    }
