如何合並兩個數組？

Question

經過循環並使用以下數組，我可以創建一個新數組。

$data[$val['gid']][$val['rid']][$val['aid']][$teno][$userid]= array();

結果是下面的數組：

array:1 [
  "FS OTHER" => array:1 [
    "FS OTHER" => array:1 [
      "FS OTHER" => array:1 [
        "FS OTHER" => array:1 [
          "D111" => []
        ]
      ]
    ]
  ]
]

我也有另一個數組：

array:41 [
  0 => array:2 [
    "sid" => "D111"
    "desc1" => "BANGKOK"
  ]
  1 => array:2 [
    "sid" => "D111"
    "desc1" => "NONTHABURI"
  ]
  2 => array:2 [
    "sid" => "D112"
    "desc1" => "PATHUM THANI"
  ]

現在，我需要基於'sid'合並此數組以獲得以下結果：

array:1 [
  "FS OTHER" => array:1 [
    "FS OTHER" => array:1 [
      "FS OTHER" => array:1 [
        "FS OTHER" => array:1 [
          "BANGKOK" => []
          "NONTHABURI"=> []
        ]
      ]
    ]
  ]
]

Answer 1

您可以准備第二個數組的另一個結構

$new = [];
foreach ($arr2 as $x) {
    $new[$x['sid']][$x['desc1']] = [];
}
// [D111 => [ BANGKOK => [], NONTHABURI => [] ],..

然后只需通過以下方式創建第一個：

$data[$val['gid']][$val['rid']][$val['aid']][$teno][$userid]= $new[$userid];
