我有一个php oauth请求，它向yahoo发送一个HTTP请求，我收到了一些私人用户信息。我可以打印出返回的内容，但如何选择单个变量？例如，我只想打印Jonathan Lucroy的名字。
以下是我用来打电话的内容：
** Heres a link to the oauth_client class for the referenced functions below **
if(strlen($client->client_id) == 0
|| strlen($client->client_secret) == 0)
die('Please go to Yahoo Apps page https://developer.apps.yahoo.com/projects/ , '.
'create a project, and in the line '.$application_line.
' set the client_id to Consumer key and client_secret with Consumer secret. '.
'The Callback URL must be '.$client->redirect_uri).' Make sure you enable the '.
'necessary permissions to execute the API calls your application needs.';
if(($success = $client->Initialize()))
{
if(($success = $client->Process()))
{
if(strlen($client->access_token))
{
$client->storeAccessToken($client->access_token);
$success = $client->CallAPI(
'http://fantasysports.yahooapis.com/fantasy/v2/team/328.l.203329.t.12/roster;week=9',
'GET', array(
'q'=>'',
'format'=>'json'
), array('FailOnAccessError'=>true), $user);
echo '<pre>';
var_dump($_SESSION);
echo '</pre>';
}
}
$success = $client->Finalize($success);
}
if($client->exit)
exit;
if(strlen($client->authorization_error))
{
$client->error = $client->authorization_error;
$success = false;
}
if($success)
{
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Yahoo OAuth client results</title>
</head>
<body>
<?php
echo '<h1>', HtmlSpecialChars($user->query->results->profile->nickname),
' you have logged in successfully with Yahoo!</h1>';
echo '<pre>', HtmlSpecialChars(print_r($user, 1)), '</pre>';
echo '<h6>'.$user.'</h6>';
?>
</body>
</html>
这就是我正在打印的内容：

Regarding this line:
if(($success = $client->Process()))
This is not a correct way to write the IF statement
The problem is an assignment always returns 'true'
A much better technique is: ( use a comparison, similar to the following)
if( false != ($success = $client->Process()) )
BTW: never compare to 'true' because 'true' can be/is defined as 'not false'
where false is 0, so any non 0 value will be 'not false'
where a compare to 'true' is looking for a specific value to match.
