最初の結果のフライト番号を表示するために、以下のコードを使用しています。

$array_data <-- The Whole above data is in this variable

$s=0;
foreach($array_data as $array)
{
echo $c=$array['AvailResponse']['OriginDestinationOptions']['OriginDestinationOption']['0']['onward']['FlightSegments']['FlightSegment']['$s']['FlightNumber'];
$s++;
}

私は何の結果も得ていません。私のコードに何か問題がありますか..?

ありがとう、ショバ。

Answer 1

1つだけ...エコーステートメントでは、$sが一重引用符(')で囲まれています。変数は、二重引用符(")で囲まれていない限り読み取られません。つまり、["$s"]。または、次のことができます。 [''.$s.''] または引用符をまとめて [$s] 削除します。

そして今、修正...

foreach($array_data['AvailResponse']['OriginDestinationOptions']['OriginDestinationOption']['0']['onward']['FlightSegments']['FlightSegment'] as $array)
{
    echo $c=$array['FlightNumber'];
}

非常にエレガントなソリューションではありませんが、機能します。

Answer 2

既知の位置でデータにアクセスしようとしています。なぜループを作成する必要があるのか​​ わかりません。

echo $array_data['AvailResponse']['OriginDestinationOptions']['OriginDestinationOption']['0']['onward']['FlightSegments']['FlightSegment']['$s']['FlightNumber'];

Answer 3

このようにしてみてください

foreach($array_data as $array)
{
    if(is_array($array))
    {
        foreach($array as $arr)
        {
             //Do the stuff
        } 
    }  
     //Do the stuff
}

配列であるかどうかを毎回確認するだけです。配列である場合は、別の foreach ループを適用します
