/(?>[^<>]+)/应该如何解释?(PHP RegExp Engine)

(?>        # I had to look this up, but apparently this syntax prevents the regex
           # parser from backtracking into whatever is matched in this group if 
           # the rest of the  pattern fails
   [^<>]+  # match ANY character except '<' or '>', 1 or more times. 
         ) # close non-backtrackable group.
