Solution in PHP (judge verdict: Accepted)

<?php
  // $x = (int)trim(fgets(STDIN));
  while(true) {
    $line = explode(" ",fgets(STDIN));
    $H = (int)$line[0];
    $W = (int)$line[1];
    if($H ==0 && $W == 0) {
      break;
    }
    for($i=0;$i<$H;$i++) {
      for($j=0;$j<$W;$j++) {
        print("#");
      }
      print("\n");
    }
    print("\n");
  }
