如何在PHP中用逗号分隔解析数学表达式的正则表达式[关闭]

Question

I have this string a,[b,c,d], e(f), g(h + i) = j, a + c = g(e)

How can I write a regex to parse it to array like below?

=> Array
     [1] => a
     [2] => [b,c,d]
     [3] => e(f)
     [4] => g(h + i) = j
     [5] => a + c = g(e)

Thanks in advance.

use preg_match_all to get the matches
