Iterating over matches from preg_match_all

Question

I am trying to figure out the mechanics of this plugin in WordPress. I have a preg_match_all function that looks like this:

preg_match_all(\'/(?<=\\\\[\\\         


        

Answer 1

If you do want to rewrite this code, then I suggest you look into PREG_SET_ORDER as last argument, instead of PREG_PATTERN_ORDER. This groups the result array by results first, and with match groups in the second level.

Then you can just loop over it as follows:

foreach ($matches as $matchgroup) {
    $postslug = $matchgroup[0];
}

You still need the [0] to get the "complete match". If your pattern had any (..) groups then [1] and [2] would correspond to those..
