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内容转换为一个字符串，但我怎样才能解析这个在PHP？我正在尝试返回“rhs”值。

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

Answer 1

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

使用json_decode

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

没有太多吧：

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

Answer 6

使用PHP的json_decode()功能：

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

echo $rhs;
