Found bug in PHP testcase

  $a1=array (  0 => 121,  1 => 144,  2 => 19,  3 => 161,  4 => 19,  5 => 144,  6 => 19,  7 => 11,);
  $a2=array (  0 => 121,  1 => 14641,  2 => 20736,  3 => 361,  4 => 25921,  5 => 361,  6 => 20736,  7 => 361,);
  $this->revTest(comp($a1, $a2), true);

It is true, but in Attemt's testBasics it is expected false - http://prntscr.com/lxt4ma .

Please, check expected result in this test in Attempt's testBasics.
