PHP访问多维数组内的属性，该数组有一个外部数组

Question

我有一个数组要遍历：

array:8132 [
  0 => {#551
  "address_id": "94e224af-135f-af31-3619-535acfae9930"
  "fiber_phase": "101"
  "parsed_hash": "1bc7fb114ee10d7cb9cea10693d238b5"
  "min_number": 400
  "max_number": 499
  "sales_rep": "164"
  "id": "abd90d6b-28a8-2be6-d6c1-abd9007aef38"
  "name": "48TH ST E"
  "block_minimum": 400
  "block_maximum": 498
}

在 foreach 中，我有另一个数组，我需要访问 if 语句的某些属性，然后将新属性添加到原始数组 ($data)：

foreach ($data as $phase) {
        $all_phases = EmeraldFiber::getPhases();
        dd($all_phases);

        if ($phase->fiber_phase === $all_phases[1]['name']) {
            $phase->fiber_status = $all_phases[1]['fiber_status'];
        }
        return $data;
    }

dd($all_phases); 看起来像这样：

array:270 [
  1 => array:7 [
    "id" => "10bc06d0-05de-07e2-b2de-5214fba5045a"
    "name" => "1"
    "description" => "50th France"
    "encoded_points" => "_sbqGnesxPJwv@iJBKpv@fJ@"
    "fiber_status" => "Live"
    "status_date" => "2010-09-01 00:00:00"

]

使用上面的 foreach，我只返回原始数组，没有新属性 fiber_status。我没有正确返回它吗？或者我是否需要映射第二个数组 ($all_phases) 才能正确访问这些属性？

Answer 1

我想你不需要return 任何东西：

// receive object once instead receiving of it multiple times
$all_phases = EmeraldFiber::getPhases();
// extract required values
$phase_name = $all_phases[1]['name'];
$phase_status = $all_phases[1]['fiber_status'];

foreach ($data as $phase) {
    if ($phase->fiber_phase === $phase_name) {
        $phase->fiber_status = $phase_status;
    }
}

// if you have this code in a function - return data here
// otherwise - you don't need return
// return $data;

更新： 如果$all_phases 是具有所有可用阶段的数组，并且您需要检查$phase->fiber_phase 是否在其中，那么您应该执行以下操作：

// receive object once instead receiving of it multiple times
$all_phases = EmeraldFiber::getPhases();
// create pairs
$phase_names = [];        
foreach ($all_phases as $item) {
    $phase_names[$item['name']] = $item['fiber_status'];
}

foreach ($data as $phase) {
    // check if `$phase->fiber_phase` exists in `$phase_names`
    if (isset($phase_names[$phase->fiber_phase])) {
        // if it does - add it's value to `$phase` object
        $phase->fiber_status = $phase_names[$phase->fiber_phase];
    }
}
