我想從上面的json中提取航班號，depScheduled，arrScheduled和旅程票價。

這是我的代碼：

$json2 = json_decode($json,true);
$result= array();
foreach ($json2['outboundOptions']['flights']as $theentity) {
    $result[] = $theentity['flightNumber'];
}
print_r($result);

上面的代碼給我一個錯誤，“為foreach（）提供了無效的參數”。我搜索過，但仍然沒有找到解決方案..

Answer 1

它給出了這個錯誤，因為outboundOptions是一個對象數組。 你想要的是訪問第一個對象：

foreach ($json2['outboundOptions'][0]['flights']as $theentity) {
    $result[] = $theentity['flightNumber'];
}

此外，刪除尾隨逗號（ ,從你） ]在端部作為使無效json 。

您可以訪問jsonlint.com查看您的json是否有效

根據您的評論更新

要獲得所有航班，請將您的foreach循環更改為：

foreach ($json3['outboundOptions'] as $flight) {
  foreach($flight['flights'] as $theentity) {
    $result[] = $theentity['flightNumber'];
  }
}

例

Answer 2

1. 刪除json末端附近的尾隨'，'。

2. 更改您的代碼，在['flights']之前添加[0] ['flights']

   $json2 = json_decode($json,TRUE); $result= array(); foreach ($json2['outboundOptions'][0]['flights']as $theentity) { $result[] = $theentity['flightNumber']; } print_r($result);
