通过 PHP 在 JSON 中查找和替换数据

Question

[
  {
    "packID": 195,
    "destinationID": 41,
    "phase": "LOC0-LOCAL"
  },
  {
    "packID": 41,
    "destinationID": 26,
    "phase": "LOC7-FLY"
  },
  {
    "packID": 42,
    "destinationID": 10,
    "phase": "LOC5-FLY"
  }
]

我想更改包号(packID) 41 的阶段和目的地。为此，我首先删除第 41 部分并添加一个新包。但是，这不能正常工作，因为数字 41 可以在其他部分。如果是这样，它会删除其他部分。我该怎么做？

$packageID = 41;

$trPackages = json_decode($jsonContent, true);
    foreach ($trPackages as $key => $value) {
        if (in_array($packageID, $value)) {
            unset($value[$key]); 
            // Result: Deleted packID:41 and packID: 195 ..
            $trPackages[] = ['packID' => 41, 'destinationID' => 99, 'phase' => 'LOC99-FLY'];
        }
    }
$trPackages = json_encode($trPackages);
...

如何只更改包 41 中的数据？

你试过了吗：

/* ... */
$trPackages = json_decode($json, true);
$packageID = 41;

foreach ($trPackages as $key => $value) {
    if ($value["packID"] == $packageID) {
        unset($trPackages[$key]); 
        // Result: Deleted packID:41 and packID: 195 ..
        $trPackages [] = ['packID' => 41, 'destinationID' => 99, 'phase' => 'LOC99-FLY'];
    }
}
