I'm trying to parse some text for example:
$text = "Blah blah [a]findme[/a] and [b]findmetoo[b], maybe also [z]me[/z].";
What I have now is:
preg_match_all("/[*?](.*?)[\/*?]/", $text, $matches);
Which doesn't work unfortunately.
Any ideas how to parse, return the node key and the corresponding node value?
Well firstly by you not putting () around your *? your not matching the tag name, and secondly, using [*?] will match multiple [ until the ] where you want to match inside, so you should be doing [(.*?)] and [\/(.*?)]
You would have to try something along the lines of:
/\[(.*?)\](.*?)\[\/(.*?)\]/is
this is not guaranteed to work but will get you closer.
you could also do:
/\[(.*?)\](.*?)\[\/\1\]/is
and then foreach result loop recursively until preg_match_all returns false, that's a possible way how to do nesting.
