PHP JSON（解码）[重复]

Question

如何通过 PHP 从此 JSON 获取“required_version”？

{
    "response": {
        "success": true,
        "up_to_date": false,
        "version_is_listable": false,
        "required_version": 13576,
        "message": "Your server is out of date, please upgrade"
    }
}

Answer 1

$json = <<<'__EOS__'
{
    "response": {
        "success": true,
        "up_to_date": false,
        "version_is_listable": false,
        "required_version": 13576,
        "message": "Your server is out of date, please upgrade"
    }
}
__EOS__;

$obj = json_decode($json);
echo $obj->response->required_version;
