如何解析网址响应？

I got response from URL like this. I want value of sid. How can I get this?

{"response": "success","body":{ "sid" : "5f255c86a", "role" : "user" }}

The above response looks to b JSON so you can use json_decode()function.

Try

$response = file_get_contents($url);
$json = json_decode($response);

echo $json->body->sid;

Note You need to replace $url with URL of response page.

It JSON format so use json_decode() function.

$response = json_decode($response);

echo $response->body->sid;

or

$response = json_decode($response, true);
echo $response['body']['sid'];

If you pass second argument as true then it will return associative array.
