无论如何要清理正则表达式捕获组？

Question

I am trying to clean up this regex capture groups because it's capturing correctly just to me it's a strange return for preg_match_all strange to me since it's first time using preg_match_all

Test Code:: http://ideone.com/7NnrI1

Regex

/(?=<!--\sBEGIN\s(.*?)\s-->(.*?)(?=<!--\sEND\s(.*?)\s-->))/s

What I need

I would like the array to be clean from the matches, so that not each capture of the same pattern are in the same array rather each time it starts capturing it'll add to the same array like in the Expected Return Thanks.

Sounds like PREG_SET_ORDER is what you want. – mario
