It seems like $seed can also be of type null; however, parameter $seed of mt_srand() does only seem to accept integer, maybe add an additional type check?
                                                                                                                                                                                           (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation

Are you sure print_r($number, true) of type string|true can be used in concatenation?

Are you sure print_r($number, true) of type string|true can be used in concatenation?
                                                                                                                                                                                           (
