I'm using Google's currency calculation api. It returns json. I can get the URL contents into a string, but how can I parse this in php? I'm trying to return the "rhs" value.

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

json_decode() is what you would use.

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

use json_decode

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

There's not much to it:

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

Use PHP's json_decode() function:

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

echo $rhs;

    Similar to Indranil, using `json_decode()` without the second parameter being true means that `$json_array` is of type Object, not of type Array. You must access members of an Object with `->` syntax. – Interrobang Dec 24 '11 at 00:18
