如何扩展正则表达式以查找多个匹配项？

Question

This is my current regex (used in parsing an iCal file):

/(.*?)(?:;(?=(?:[^"]*"[^"]*")*[^"]*$))([\w\W]*)/

The current output using preg_match() is this:

//Output 1 - `preg_match()`
Array
(
    [0] => TZID="Greenwich Mean Time:Dublin; Edinburgh; Lisbon; London"
    [1] => VALUE=DATE;RSVP=FALSE;LANGUAGE=en-gb
)

I would like to extend my regex to output this (i.e. find multiple matches):

//Output 2
Array
(
    [0] => TZID="Greenwich Mean Time:Dublin; Edinburgh; Lisbon; London"
    [1] => VALUE=DATE
    [2] => RSVP=FALSE
    [3] => LANGUAGE=en-gb
)    

The regex should search for each semicolon not contained within a quoted substring and provide that as a match.

Cannot just swap to preg_match_all() as gives this unwanted output

//Output 3 - `preg_match_all()`
Array
(
    [0] => Array
        (
            [0] => TZID="Greenwich Mean Time:Dublin; Edinburgh; Lisbon; London";VALUE=DATE;RSVP=FALSE;LANGUAGE=en-gb
        )

    [1] => Array
        (
            [0] => TZID="Greenwich Mean Time:Dublin; Edinburgh; Lisbon; London"
        )

    [2] => Array
        (
            [0] => VALUE=DATE;RSVP=FALSE;LANGUAGE=en-gb
        )

)

(.+?)(?:;(?=(?:[^"]*"[^"]*")*[^"]*$)|$)

Try this.See demo.
