How to validate text using regular expressions?

Question

PHP

Good evening!
Please tell me how you can compose a regular expression to check the text, according to a given pattern:
number time time time time time
number time time time time time
01 01:00 02:00 03:00 04:00 05:00
02 01:00 02 :00 03:00 04:00 05:00
03 01:00 02:00 03:00 04:00 05:00
04 01:00 02:00 03:00 04:00 05:00
05 01:00 02:00 03:00 04:00 05:00
and if there is at least one extra character in the string, except for spaces, then the check was unsuccessful,
I almost got to the point, but I'm missing something regex101
It is necessary to check the entire string

Answer 1

var str ="01 01:00 02:00 03:00 04:00 05:00 \n02 01:00 02:00 03:00 04:00 05:00\n03 01:00 02:00 03:00 04:00 05:00\n04 01:00 02:00 03:00 04:00 05:00  \n05 01:00 02:00 03:00 04:00 05:00";

if(str.match(/^(\d{1,2}\s+(\d{1,2}\:\d{1,2}\s+){4}\d{1,2}\:\d{1,2}(\s?)+)+$/m)[0] != str)
  console.log("проверка прошла неудачно");
  else
  console.log("проверка прошла удачно")
