The problem is somewhere in the code, and you don't show any code!  This
PHP:

  $a = [
       ["(Jan 7, 2015 0:42AM)","2015-01-06 15:43:00","this is string 1."],
       ["(Jan 7, 2015 0:42AM)","2015-01-06 15:42:26","this is string 2"]
  ];
  echo json_encode($a);

correctly outputs (sorry about the long line):

[["(Jan 7, 2015 0:42AM)","2015-01-06 15:43:00","this is string 1."],["(Jan 7, 2015 0:42AM)","2015-01-06 15:42:26","this is string 2"]]

And this is correctly parsed by JSON.parse:

JSON.parse('[["(Jan 7, 2015 0:42AM)","2015-01-06 15:43:00","this is string 1."],["(Jan 7, 2015 0:42AM)","2015-01-06 15:42:26","this is string 2"]]')

produces:

[ [ '(Jan 7, 2015 0:42AM)',
    '2015-01-06 15:43:00',
    'this is string 1.' ],
  [ '(Jan 7, 2015 0:42AM)',
    '2015-01-06 15:42:26',
    'this is string 2' ] ]

I suspect some problem to do with quotes in the way you get the string
from PHP to JavaScript.
