The tests are okay.

Your current solution doesn't meet the expected condition:

If your total is more than or equal to (win), return 'Winner!'. Else return 'Loser!'.

not an issue.

In PHP, I earned the test, but when I try to attempt it failed !
Is there a bug ?

Debug here :

array(3) {
  [0]=>
  array(2) {
    [0]=>
    string(3) "ABC"
    [1]=>
    int(65)
  }
  [1]=>
  array(2) {
    [0]=>
    string(3) "HGR"
    [1]=>
    int(74)
  }
  [2]=>
  array(2) {
    [0]=>
    string(4) "BYHT"
    [1]=>
    int(74)
  }
}
string(7) "win = 2"
string(9) "Result : "
string(8) "in = ABC"
string(10) "Search : A"
string(9) "Result : "
string(8) "in = HGR"
string(10) "Search : J"
string(9) "Result : "
string(9) "in = BYHT"
string(10) "Search : J"
string(10) "Result = 1"
string(12) "Attenmpt = 2"
