PHP Regexp for Nested Parentheses

I have a chunk of text in the form:

some text (more (text) with (possible nested) parentheses) (yet more (text) with (possible nested) parentheses) final text

I want to get the first set of nested parentheses i.e.

 (more (text) with (possible nested) parentheses)

I've tried preg_match("/\(([^\)]+|(?R))\)*/is",$text,$matches) but it gives me all the parenthses i.e.

(more (text) with (possible nested) parentheses) (yet more (text) with (possible nested) parentheses)

I've also tried preg_match("/\(([^\)]+|(?R))\)*/is",$text,$matches) but this produces eratic results (sometimes chopping off stuff after a nested closing parenthesis, sometimes not).

Any sugestions?

if rhe parentheses are only nested two deep, you could do
guyharleyausAuthor Commented:
The parentheses can be nest multiple layers e.g.

(some (text (with (nested) parentheses) and) (other stuff))
