Split a CSV string only containing single-quoted values into a two-element array

Question

I have a string that looks like this:

'word','another word','and a sentence','and more','etc etc'

I need to split this into two strings, divided by the second comma -- which shouldn't show in either of the sentences. What complicates things is that here can also be commas inside the various quotes parts of the string.

Answer 1

$a="'word','another word','and a sentence','and more','etc etc'";

//preg_match('{(.*?,[^,]*),(.*)}', $a, $matches);
preg_match('{(.*?[^\\\\]\',.*?[^\\\\]\'),(.*)}', $a, $matches); //UPDATE 
print_r($matches);

DISPLAY:

    Array
(
    [0] => 'word','another word','and a sentence','and more','etc etc'
    [1] => 'word','another word'
    [2] => 'and a sentence','and more','etc etc'
)
