testtongji.php 整理返回的数据

Question

testtongji.php 代码如下

<?php error_reporting(0);

$url = 'https://www.zzxxxx.xx/api/wetds/stats/';

$options = array(
    'http' => array(     
        'header'  => "Content-Type: application/json",
        'header'  => "Authorization: Token 633b4deb1cd517a01851a3335811b9ae8e1d6d6d",
        'method'  => 'GET',
        'content' => http_build_query
    )
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);

echo ($result);

 

打开testtongji.php  返回数据如下
{"bandwidth_used":393073846353,"bandwidth_remaining":680667977647.0,"bandwidth_limit":1073741824000.0,"bandwidth_projected":1496203172977,"last_request_at":"2021-01-13T01:59:38.381732-08:00","requests_total":239278,"requests_successful":238115,"requests_failed":1163,"request_countries":{"US":238334,"NL":848,"RS":96},"requests_error_reasons":{"target_read_deadline":1142,"target_connect_timeout":12,"client_read_timeout":2,"client_read_eof":7},"request_failure_status_codes":{}}

echo ($result);整理如下
需要把以上返回的数据整理为以下内容    bandwidth_used":393073846353,"bandwidth_remaining":680667977647.0      计算出393073846353字节 =多少GB      680667977647.0字节==多少GB  像下面这样展示出，其他的数据都不要    
已用流量： XXXX   GB
剩余流量： XXXX   GB

$options = array(
    'http' => array(     
        'header'  => "Content-Type: application/json",
        'header'  => "Authorization: Token 633b4deb1cd517a01851a3335811b9ae8e1d6d6d",
        'method'  => 'GET',
        'content' => http_build_query
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);

$arr = json_decode($result,true);
//1GB = 1024MB,1MB=1024KB.1KB=1024Bit
echo "已用流量: ";
echo $arr['bandwidth_used'] = $arr['bandwidth_used']/(1024*1024*1024) .' GB';
echo "<br>";
echo "剩余流量: ";
echo $arr['bandwidth_remaining'] = $arr['bandwidth_remaining']/(1024*1024*1024) .' GB';
?>
