无法检索Json信息

Question

尝试检索JSON数组，但页面只是回显“Null”

以下是我用来检索Json变量的代码

    <?php
function getSystem($address)

    {

        $data_location = "/r10database/checkSystem/index.php?theaddress=".$address;
        $data = file_get_contents($data_location);


        $data = json_decode($data);

        $system = $data->system;

        var_dump($system);



    }
getSystem("Blvd");
?>

这是我的代码来编码我的json变量

function changeElement(contentString,address){


var addressObject = new Array();
addressObject[0]=contentString;

var json_str = JSON.stringify(addressObject); 
var obj = JSON.parse(json_str)

  $('#insertHere').html(json_str);

}
