Your function *echos the output*, it doesn't *`return`* it to the caller, so there's nothing to assign to `$hastalikSONUC`. You need to concatenate a string and `return` it instead of just `echo`ing it. – deceze Jul 07 '21 at 06:39
Can you show in example like my function please? – Edursun Jul 07 '21 at 06:54
`$str = 'Have ...'; $str .= "YES"; ... return $str` – deceze Jul 07 '21 at 06:58

Update your question to show your attempt. – deceze Jul 07 '21 at 07:04
i did but still closed :( – Edursun Jul 07 '21 at 07:13
Where are you concatenating and `return`ing a string here?! – deceze Jul 07 '21 at 07:16
in function if and else lines like " $str = $value." : YES
"; return $str; } else { $str = $value." : NO
"; return $str; ........ Like this but return one result not loop... – Edursun Jul 07 '21 at 07:22
`$str = 'Have ...'; foreach (...) { $str .= "..."; } return $str;` — *Concatenate* inside the loop, *`return`* after the loop. – deceze Jul 07 '21 at 07:25
