Regex - Match separated numbers

Question

Matching the regex /^(?:\.(\d{3}))*$/s on .234.567 produces the following output:

array (size=2)
  0 => 
    array (size=1)
      0 => string '.234.567' (length=8)
  1 => 
    array (size=1)
      0 => string '567' (length=3)

Why is 234 not listed in the second subarray?

Answer 1

As @develroot already has answered the way you want to use preg_match_all does not work, it will only return the last matching group, not all captures of that group. That's how regex works.
