在php中解码json

Question

我正在使用Google的货币计算API。它返回json。我可以将URL内容转换为字符串，但是如何在php中解析它？我试图返回“rhs”值。

    $string='{lhs: "1 Euro",rhs: "1.3067 U.S. dollars",error: "",icc: true}'; 
    $rhs=?????
    echo $rhs; 

Answer 1

json_decode()就是你要用的。

$data = json_decode($string);
$rhs = $data->rhs;

Answer 2

使用json_decode

$rhs = json_decode($string);
// $rhs is an object now.

没有太多内容：

$obj = json_decode($string);
$rhs = $obj->rhs;

Answer 6

使用PHP的json_decode()函数：

$string      = '{lhs: "1 Euro",rhs: "1.3067 U.S. dollars",error: "",icc: true}';
$json_object = json_decode($string);
$rhs         = $json_array->rhs;

echo $rhs;
