array (     [0] => array         (             [0] => 78             [mount] => 78             [1] => activation             [type] => activation             [2] => 2013-10-01             [insertdate] => 2013-10-01         )      [1] => array         (             [0] => 130             [mount] => 130             [1] => activation             [type] => activation             [2] => 2013-10-02             [insertdate] => 2013-10-02         )      [2] => array         (             [0] => 210             [mount] => 210             [1] => activation             [type] => activation             [2] => 2013-10-03             [insertdate] => 2013-10-03         )      [3] => array         (             [0] => 190             [mount] => 190             [1] => activation             [type] => activation             [2] => 2013-10-04             [insertdate] => 2013-10-04         )      [4] => array         (             [0] => 250             [mount] => 250             [1] => activation             [type] => activation             [2] => 2013-10-05             [insertdate] => 2013-10-05         )      [5] => array         (             [0] => 300             [mount] => 300             [1] => activation             [type] => activation             [2] => 2013-10-06             [insertdate] => 2013-10-06         )      [6] => array         (             [0] => 330             [mount] => 330             [1] => activation             [type] => activation             [2] => 2013-10-07             [insertdate] => 2013-10-07         )      [7] => array         (             [0] => 100             [mount] => 100             [1] => revenue             [type] => revenue             [2] => 2013-10-01             [insertdate] => 2013-10-01         )      [8] => array         (             [0] => 310             [mount] => 310             [1] => revenue             [type] => revenue             [2] => 2013-10-02             [insertdate] => 2013-10-02         )      [9] => array         (             [0] => 200             [mount] => 200             [1] => revenue             [type] => revenue             [2] => 2013-10-03             [insertdate] => 2013-10-03         )      [10] => array         (             [0] => 400             [mount] => 400             [1] => revenue             [type] => revenue             [2] => 2013-10-04             [insertdate] => 2013-10-04         )      [11] => array         (             [0] => 470             [mount] => 470             [1] => revenue             [type] => revenue             [2] => 2013-10-05             [insertdate] => 2013-10-05         )      [12] => array         (             [0] => 310             [mount] => 310             [1] => revenue             [type] => revenue             [2] => 2013-10-06             [insertdate] => 2013-10-06         )      [13] => array         (             [0] => 600             [mount] => 600             [1] => revenue             [type] => revenue             [2] => 2013-10-07             [insertdate] => 2013-10-07         )  )

the goal convert 1 dimension array result as:

array([type]=>activation [mount]=>78,130,210,190,250,300,330), array([type]=>revenue [mount]=>100,310,200,400,470,310,600)

there simple way php4 , newer, function called array_merge_recursive(). merge sub arrays single one. if there identical keys, merged single key array value.

see full documentation here.
