使用php连接单个数组

Question

我有一个样本数组。我想合并为单行作为标题，并将值添加到下面的相应标题中。我已经尝试过，但是我的运气不好。在下面，我共享示例数组。

(

        [0] => Array(
                [sno] => 1,
                [datetime] => 2019-06-23 12:00:05,
                [dkey] => EMIUnit1P575011 2659,
                [ID1 Rotary GearBox  Line to neutral voltage VLN] => 242,
                [ID1 Rotary GearBox Current average A] => 0,
                [ID1 Rotary GearBox  Active power total W] => 524
            )   
    [1] => Array(
                [sno] => 2,
                [datetime] => 2019-06-23 11:45:04,
                [dkey] => EMIUnit1P575011 2658,
                [ID1 Rotary GearBox  Line to neutral voltage VLN] => 241,
                [ID1 Rotary GearBox Current average A] => 7,
                [ID1 Rotary GearBox  Active power total W] => 2546
            )
    [2] => Array(
                [sno] => 3,
                [datetime] => 2019-06-23 11:30:04,
                [dkey] => EMIUnit1P575011 2657,
                [ID1 Rotary GearBox  Line to neutral voltage VLN] => 241,
                [ID1 Rotary GearBox Current average A] => 22,
                [ID1 Rotary GearBox  Active power total W] => 2475
            )
    [3] => Array(
                [sno] => 1
                [datetime] => 2019-06-23 12:00:26,
                [dkey] => D0B5C2C17EAF_B2.0 2,
                [voltage] => 232
                [Amps] => 2,
                [Power] => 296
            )
    [4] =>Array
    (
     [sno] => 2,
     [datetime] => 2019-06-23 11:45:25,
     [dkey] => D0B5C2C17EAF_B2.0 1,
     [voltage] => 232,
     [Amps] => 0,
     [Power] => 200
     )
    )

我已经尝试过，但是我不确定逻辑。请帮助我实现这一目标。 预期的数组如下所示

(
    [0] => Array
        (
            [sno] => 1
            [datetime] => 2019-06-23 12:00:05
            [dkey] => EMIUnit1P575011 2659
            [ID1 Rotary GearBox  Line to neutral voltage VLN] => 242
            [ID1 Rotary GearBox Current average A] => 0
            [ID1 Rotary GearBox  Active power total W] => 524
            [voltage] => 232
            [Amps] => 2
            [Power] => 296
        )

    [1] => Array
        (
            [sno] => 2
            [datetime] => 2019-06-23 11:45:04
            [dkey] => EMIUnit1P575011 2658
            [ID1 Rotary GearBox  Line to neutral voltage VLN] => 241
            [ID1 Rotary GearBox Current average A] => 7
            [ID1 Rotary GearBox  Active power total W] => 2546
            [voltage] => 232
            [Amps] => 0
            [Power] => 200
        )

    [2] => Array
        (
            [sno] => 3
            [datetime] => 2019-06-23 11:30:04
            [dkey] => EMIUnit1P575011 2657
            [ID1 Rotary GearBox  Line to neutral voltage VLN] => 241
            [ID1 Rotary GearBox Current average A] => 22
            [ID1 Rotary GearBox  Active power total W] => 2475
        )
