turn cURL json array response to an associate array
提问by vinylDeveloper
I have a cURL request like so
我有一个像这样的 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>
This is what it prints.

json_decodegives you an associative array when you pass "true" as the second argument:
json_decode当您将“true”作为第二个参数传递时，会为您提供一个关联数组：
$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"];
gives:
给出：
Test
Edit:
编辑：
json_decode()is giving you back an array of arrays, so you need to reference the array that is at position [0]in the response, if you get me.
json_decode()正在给你一个数组数组，所以你需要引用[0]响应中位置的数组，如果你得到我的话。
I've done that above in my example with $response[0], but have a look at this example, hope it makes it clearer!
我在上面的例子中用 $response[0] 做了这个，但是看看这个例子，希望它更清楚！
$result = json_decode($json, true);
var_dump($result);
gives:
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)
}
}
}
then.. to access the array itself:
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);
gives:
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)
}
}
And now you can access the various elements of the array directly:
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";
now we get back:
现在我们回来了：
Name: Test
ID: 1079
Description: This is a Test Event
hope that makes sense!
希望这是有道理的！

By default curl_exec outputs the data it gets from the server to the standard output so your $response variable doesn't really have the actual response data in it. If you want to get the data in a variable set the CURLOPT_RETURNTRANSFER option before calling curl_exec.
默认情况下 curl_exec 会将它从服务器获取的数据输出到标准输出，因此您的 $response 变量中并没有真正的响应数据。如果要在变量中获取数据，请在调用 curl_exec 之前设置 CURLOPT_RETURNTRANSFER 选项。
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE)
