在PHP中用逗号分解复杂的字符串

Question

I need to split a string that contains commas. I already found something for strings like (str_getcsv):

'A', 'B with a comma, eh', 'C'

But my string is like this, e.g. with no enclosing characters for the values:

A, B (one, two), C

I need to explode this and obtain:

array(3) {
  [0]=>
  string(1) "A"
  [1]=>
  string(12) "B (one, two)"
  [2]=>
  string(1) "C"
}

I want to split the string using the commas that are not inside parentheses, because that is the only one case in my situation when explode fails.

Answer 1

But there is a solution for your crazy wish ;)

$a = "(Z) X, (Y, W) A, B (one, two), C, D (E,F,G) H, I J";
$reg = '/[^(,]*(?:\([^)]+\))?[^),]*/';
preg_match_all($reg, $a, $matches);
$result = array_filter($matches[0]);
var_dump($result);
