这里我有如下json输出。我想做的是，我想将scope、production、refreshtoken和access_token作为var_dump输出的独立php变量。

这是json输出

array ( 'status' => 'OK', 'statusCode' => 200, 'time' => 1.628268, 'header' => array ( 0 => 'HTTP/1.1 200 OK Date: Fri, 06 May 2016 06:22:42 GMT Server: O2-PassThrough-HTTP Content-Type: application/json Pragma: no-cache Cache-Control: no-store Transfer-Encoding: chunked ', ), 'body' => '{"scope":"TARGET","token_type":"bearer","expires_in":2324,"refresh_token":"4567f358c7b203fa6316432ab6ba814","access_token":"55667dabbf188334908b7c1cb7116d26"}', )

这是我的php

var_dump($r);
echo $var[0]."<br>";
echo $var[1]."<br>";
echo $var[2]."<br>";
echo $var[3]."<br>";
echo $var[4]."<br>";
echo $var[5]."<br>";
echo $var[6]."<br>";
echo $var[7]."<br>";
echo $var[8]."<br>";

您可以使用json_decode并提取：

<?php
$a = array ( 'status' => 'OK', 'statusCode' => 200, 'time' => 1.628268, 'header' => array ( 0 => 'HTTP/1.1 200 OK Date: Fri, 06 May 2016 06:22:42 GMT Server: O2-PassThrough-HTTP Content-Type: application/json Pragma: no-cache Cache-Control: no-store Transfer-Encoding: chunked ', ), 'body' => '{"scope":"TARGET","token_type":"bearer","expires_in":2324,"refresh_token":"4567f358c7b203fa6316432ab6ba814","access_token":"55667dabbf188334908b7c1cb7116d26"}', );
$body = json_decode($a['body'], TRUE);
extract($body); //Extracts array keys and converts to variables
echo $scope;
echo $token_type;
echo $expires_in;
echo $refresh_token;
echo $access_token;

输出：

TARGET
bearer
2324
4567f358c7b203fa6316432ab6ba814
55667dabbf188334908b7c1cb7116d26

这一点都不难。您只需要json_decode()当前的JSON并获取所需的字段：

$data = json_decode($json['body']);
$scope = $data->scope;
//....etc

示例/演示

您的数组：

$arr = array ( 'status' => 'OK', 'statusCode' => 200, 'time' => 1.628268, 'header' => array ( 0 => 'HTTP/1.1 200 OK Date: Fri, 06 May 2016 06:22:42 GMT Server: O2-PassThrough-HTTP Content-Type: application/json Pragma: no-cache Cache-Control: no-store Transfer-Encoding: chunked ', ), 'body' => '{"scope":"TARGET","token_type":"bearer","expires_in":2324,"refresh_token":"4567f358c7b203fa6316432ab6ba814","access_token":"55667dabbf188334908b7c1cb7116d26"}');

只需解码你的阵列的身体部分。

你得到了这个：

$json = $arr['body'];
$arr2 = json_decode($json);
print_r($arr2);
stdClass Object
(
    [scope] => TARGET
    [token_type] => bearer
    [expires_in] => 2324
    [refresh_token] => 4567f358c7b203fa6316432ab6ba814
    [access_token] => 55667dabbf188334908b7c1cb7116d26
)

现在访问这个数组并从中获取所有值。

foreach($arr2 as $key => $value){
    echo $key." => ".$value."<br/>";
}

结果

scope => TARGET
token_type => bearer
expires_in => 2324
refresh_token => 4567f358c7b203fa6316432ab6ba814
access_token => 55667dabbf188334908b7c1cb7116d26
