Question

以下代码对我有用，但它只给我一个自动完成的密钥。如何显示两个键并打印它们。在我的情况下，我打算在建议框中打印国家名称和费率。

任何帮助都将受到高度赞赏。

print $jsonWrite;
?>

Answer 1

你可以通过
来做 $json_arr["name"] = $recResult['CountryName']." ".$recResult['SellingRate'];

Answer 2

可能你正在寻找这样的东西：

$json_arr["name"] = $recResult['CountryName'].' '.$recResult['SellingRate'];

或者可能是这种组合：

$json_arr["name"] = $recResult['CountryName'].' '.$recResult['SellingRate'];
$json_arr["value"] = $recResult['CountryName'].' '.$recResult['SellingRate'];
