这/ /(* MARK:A)/正则表达式功能是什么?

What is the name of this regex feature, and is there any documenation about it (PHP specific or not)?

preg_match('/(*MARK:A)a/', 'a', $matches);

    This is documented in the PCRE pattern documentation, search for "Recording which path was taken" on that page. It appears to be a fairly specific feature and it wouldn't be useful in the example you have provided.
