Okay, the err is coming form this line

foreach ($errors as $error){

The problem is that $errors is not an array, most likely caused by this error happening

        if (valid_credentials($_POST['username'], $_POST['password']) === false){
            $errors = 'Up.ime: / Geslo: neplavilno.';
        }

Since here you just define $errors as a string instead of adding a string to the existing array, it should be

        if (valid_credentials($_POST['username'], $_POST['password']) === false){
            $errors[] = 'Up.ime: / Geslo: neplavilno.';
        }
