foreachを使用してJSONを多次元配列で出力する

こんにちは私はBing Web検索APIを使用していますので、PHPを使用してJSONをhtmlに翻訳すると助けが必要です。 foreach（）とif（）ステートメントを使って選択的なスタッフを印刷できるようになりました。私は他のエントランスで見てきましたが、何が問題か分かりません。ここで foreachを使用してJSONを多次元配列で出力する

は、JSONの例である：私は次のエラーを取得しています

$links = json_decode($json, TRUE); 

foreach ($links['webPages'] as $j => $v) { 
    if($j=="value"){ 
     foreach ($v as $k => $w) { 
      print $k . ": " . $w; 
     } 
    } 

}

：私は、私は次のPHPコードを使用しています内部の「ウェブページ」をいくつかのものを印刷したい
