Question

需要帮助以使用两个数组制作新数组。一个数组是

 array:2 [▼
  "Date Date 2018-07-23" => array:1 [▼
    6 => array:2 [▼
      "avg" => 0.0
      "line_n0" => 6
    ]
  ]
  "Date Date 2018-07-28" => array:3 [▼
    1 => array:2 [▼
      "avg" => 0.031472222222222
      "line_n0" => 1
    ]
    4 => array:2 [▼
      "avg" => 0.011111111111111
      "line_n0" => 4
    ]
    5 => array:2 [▼
      "avg" => 0.011111111111111
      "line_n0" => 5
    ]
  ]
]

另一个数组是

        array:6 [▼
          1 => array:2 [▼
            "avg" => 0
            "line_n0" => 1
          ]
          2 => array:2 [▼
            "avg" => 0
            "line_n0" => 2
          ]
          3 => array:2 [▼
            "avg" => 0
            "line_n0" => 3
          ]
          4 => array:2 [▼
            "avg" => 0
            "line_n0" => 4
          ]
          5 => array:2 [▼
            "avg" => 0
            "line_n0" => 5
          ]
          6 => array:2 [▼
            "avg" => 0
            "line_n0" => 6
          ]



    array:2 [▼
      "Date Date 2018-07-23" => array:1 [▼
        1 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
    2 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
    3 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
    4 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
    5 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
        6 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
      ]
      "Date Date 2018-07-28" => array:3 [▼
        1 => array:2 [▼
          "avg" => 0.031472222222222
          "line_n0" => 1
        ]
    2 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
    3 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
        4 => array:2 [▼
          "avg" => 0.011111111111111
          "line_n0" => 4
        ]
        5 => array:2 [▼
          "avg" => 0.011111111111111
          "line_n0" => 5
        ]
    6 => array:2 [▼
          "avg" => 0.0
          "line_n0" => 6
        ]
      ]
    ]

请帮助我如何组合数组，如果没有第一个数组key的帮助，我想推送第二个数组元素。我尝试但不清楚制作新数组。我已经尝试了数组合并和数组合并，但是不清楚是否可以创建这个新数组。

使用下面的array_merge（）函数示例

<?php
      $array1 = array("color" => "red", 2, 4);
      $array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
      $result = array_merge($array1, $array2);
      print_r($result);
?>

输出如下：

Array
(
    [color] => green
    [0] => 2
    [1] => 4
    [2] => a
    [3] => b
    [shape] => trapezoid
    [4] => 4
)

需要制作新数组
