PHP error in `gettype`

Question

I am PHP developer and I am trying to use following code but I don't know I am getting wrong error in PHP 7 but it's working fine at PHP 5:

$output = 5;
echo gettype($output);

The output is:

integerarray

Your code outputs integer. Your array output seems to come from another code. — Syscall

Yes, But I don't know I am getting integerarray. Actually I am giving an test on app.codility.com/demo/take-sample-test I write following code but its giving me output as array which should not be . function solution($n,$A) { // write your code in PHP7.0 if($n<0){ $output = 1; }else{ $output = $n; } if($output==in_array($output,$A)){ $output++; solution($output,$A); }else{ echo $output; } } $A = array(1,3,6,4,1,2); solution(min($A),$A);
