Question

我有这样的cURL请求

$ch = curl_init();
$data = 'filter=year(StartTime)' . urlencode(' eq 2013 and ') .'month(StartTime)'. urlencode(' eq 06') ;
curl_setopt($ch, CURLOPT_URL, "http://url.com/id()/events?$".$data);
$headers = array(
    'Accept: application/json',
    'Content-type: application/json',
    'X-ApiKey : XXXXXXXXXX'
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, false);

$response = curl_exec($ch);
curl_close($ch);
$result = json_decode($response, true);

?>
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>


</head>

<body>

<br><br>
<?php 
 echo "the name". $result['Name'];
?>

</body>
</html>

这是它打印的内容。

HTTP/1.1 200 OK Cache-Control: no-cache Pragma: no-cache Content-Length: 218 Content-Type: application/json; charset=utf-8 Expires: -1 Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET- WEBSRV X-Powered-By: ARR/2.5 X-Powered-By: ASP.NET - ARR02 Date: Mon, 01 Jul 2013 02:52:31 GMT [{"Id":1079,"Name":"Test ","Status":1,"MemberId":1308,"Description":"This is a Test Event","SponsoredBy":null,"StartTime":"2013-06-30T12:00:00","EndTime":"2013-06-30T23:59:00","SearchDescription":null,"Types":[1,4,6]}] 

the name

如何将其置于关联数组中？

我试过这个

json_decode($response,true));

和这个

ksort($response);

和这个

var_dump($response);

似乎没有任何作用..

我希望能够像这样输出

echo $reponse['Name'];

有任何帮助吗？感谢

json_decode在you pass "true" as the second argument：

时为您提供关联数组

  $json = '[{"Id":1079,"Name":"Test ","Status":1,"MemberId":1308,"Description":"This is a Test Event","SponsoredBy":null,"StartTime":"2013-06-30T12:00:00","EndTime":"2013-06-30T23:59:00","SearchDescription":null,"Types":[1,4,6]}]';

  $response = json_decode($json, true);

  echo $response[0]["Name"];

给出：

Test

修改

json_decode()会返回一个数组数组，因此如果你找到我，你需要在响应中引用位于[0]的数组。

我已经在我的例子中用$ response [0]完成了这个，但看看这个例子，希望它能让它更清晰！

$result = json_decode($json, true); var_dump($result);

给出：

array(1) { [0]=> array(10) { ["Id"]=> int(1079) ["Name"]=> string(5) "Test " ["Status"]=> int(1) ["MemberId"]=> int(1308) ["Description"]=> string(20) "This is a Test Event" ["SponsoredBy"]=> NULL ["StartTime"]=> string(19) "2013-06-30T12:00:00" ["EndTime"]=> string(19) "2013-06-30T23:59:00" ["SearchDescription"]=> NULL ["Types"]=> array(3) { [0]=> int(1) [1]=> int(4) [2]=> int(6) } } }

然后..访问数组本身：

$result = json_decode($json, true); $result = $result[0]; // let's just reassign this to get the array we want var_dump($result);

给出：

array(10) { ["Id"]=> int(1079) ["Name"]=> string(5) "Test " ["Status"]=> int(1) ["MemberId"]=> int(1308) ["Description"]=> string(20) "This is a Test Event" ["SponsoredBy"]=> NULL ["StartTime"]=> string(19) "2013-06-30T12:00:00" ["EndTime"]=> string(19) "2013-06-30T23:59:00" ["SearchDescription"]=> NULL ["Types"]=> array(3) { [0]=> int(1) [1]=> int(4) [2]=> int(6) } }

现在您可以直接访问数组的各种元素：

$result = json_decode($json, true); $result = $result[0]; echo "Name: ". $result["Name"] . "\nID: " . $result["Id"] . "\nDescription: " . $result["Description"] . "\n";

现在我们回来了：

Name: Test ID: 1079 Description: This is a Test Event

希望有意义！

Answer 2

默认情况下，curl_exec将从服务器获取的数据输出到标准输出，因此$ response变量实际上没有实际的响应数据。如果要在变量中获取数据，请在调用curl_exec之前设置CURLOPT_RETURNTRANSFER选项。

curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE)

将cURL json数组响应转换为关联数组
