Question

php > preg_match("@/m(/[^/]+)+/t/?@", "/m/part/other-part/t", $m);
php > var_dump($m);
array(2) {
  [0]=>
  string(20) "/m/part/other-part/t"
  [1]=>
  string(11) "/other-part"
}
php > preg_match_all("@/m(/[^/]+)+/t/?@", "/m/part/other-part/t", $m);
php > var_dump($m);
array(2) {
  [0]=>
  array(1) {
    [0]=>
    string(20) "/m/part/other-part/t"
  }
  [1]=>
  array(1) {
    [0]=>
    string(11) "/other-part"
  }
}

With said example I would like the capture to match both /part and /other-part, unfortunately with regex /m(/[^/]+)+/t/? doesn’t capture both, as I expect.

This capture should not be bound to only match this sample, it should capture an undefined number of repetitions of the capture group; e.g. /m/part/other-part/and-another/more/t

UPDATE:
Given that this is expected behavior my question stands as of how I would be able to achieve this matching of mine?

Try this one out:

preg_match_all("@(?:/m)?/([^/]+)(?:/t)?@", "/m/part/other-part/another-part/t", $m);
var_dump($m);

It gives:

array(2) {
  [0]=>
  array(3) {
    [0]=>
    string(7) "/m/part"
    [1]=>
    string(11) "/other-part"
    [2]=>
    string(15) "/another-part/t"
  }
  [1]=>
  array(3) {
    [0]=>
    string(4) "part"
    [1]=>
    string(10) "other-part"
    [2]=>
    string(12) "another-part"
  }
}

//EDIT

IMO the best way to do what you want is to use preg_match() from @stema and explode result by / to get list of parts you want.
