I was trying to solve the kata called "are they the same". When I tap test, everything’s working properly. However, when I try to attempt the answer, it says, I have wrong answers (for example true, when the right answer is false)

The kata

Given two arrays a and b write a function comp(a, b) (orcompSame(a,

b)) that checks whether the two arrays have the "same" elements, with

the same multiplicities. "Same" means, here, that the elements in b

are the elements in a squared, regardless of the order.Examples Valid arrays a = [121, 144, 19, 161, 19, 144, 19, 11] b =

[121, 14641, 20736, 361, 25921, 361, 20736, 361] comp(a, b) returns

true because in b 121 is the square of 11, 14641 is the square of 121,

20736 the square of 144, 361 the square of 19, 25921 the square of

161, and so on. It gets obvious if we write b’s elements in terms of

squares:a = [121, 144, 19, 161, 19, 144, 19, 11] b = [11

11, 121121,

144144, 1919, 161161, 1919, 144144, 1919] Invalid arrays If, for

example, we change the first number to something else, comp may not

return true anymore:a = [121, 144, 19, 161, 19, 144, 19, 11] b = [132, 14641, 20736,

361, 25921, 361, 20736, 361] comp(a,b) returns false because in b 132

is not the square of any number of a.a = [121, 144, 19, 161, 19, 144, 19, 11] b = [121, 14641, 20736,

36100, 25921, 361, 20736, 361] comp(a,b) returns false because in b

36100 is not the square of any number of a.Remarks a or b might be [] or {} (all languages except R, Shell). a or

b might be nil or null or None or nothing (except in C++, Crystal,

Dart, Elixir, Fortran, F#, Haskell, Nim, OCaml, Pascal, Perl,

PowerShell, Prolog, PureScript, R, Racket, Rust, Shell, Swift). If a

or b are nil (or null or None, depending on the language), the problem

doesn’t make sense so return false.Note for C The two arrays have the same size (> 0) given as parameter

in function comp.

Here is my code

```
function comp($a1, $a2) {
if(!isset($a1) || !isset($a2)) return false;
if(is_null($a1) || is_null($a2)) return false;
if(empty($a1) && empty($a2)) return true;
if(!$a1 && !$a2) return false;
$match = false;
foreach($a2 as $num2){
$match = false;
foreach($a1 as $num1){
if($num2 < 0){
$match = false;
break(2);
}
if($num2 == (float)$num1*(float)$num1){
$match = true;
break;
}
else{
$match = false;
}
}
if($match == false){
return false;
}
}
if($match == false){
return false;
}
return true;
}
```

Can you please help me find the problem. I tried a lot of stuff and have no clue what is working unproperly.
