我尝试使用PHP和MongoDB实现Google登录。每当我尝试执行$manager->executeQuery时，我都会收到Fatal错误，指出它无法执行。
$cursor = $manager->executeQuery($this->dbName.'.'.$this->userTbl, $prevQuery);
我不知道如何调试这个程序。这是我的代码示例：
class User {
private $dbHost = "localhost:27017";
private $dbName = "Demo";
private $userTbl = 'google_users';
function __construct(){
//Connecting to MongoDB
try {
$manager = new MongoDB\Driver\Manager( 'mongodb://'. $this->dbHost );
}
catch (MongoDB\Driver\Exception\Exception $e) {
echo $e->getMessage(), "\n";
}
}
function checkUser($userData = array()){
if(!empty($userData)){
//Check whether user data already exists in database
$filter = ['oauth_uid' => $userData['oauth_uid'], 'oauth_provider' => $userData['oauth_provider']];
$prevQuery = new MongoDB\Driver\Query($filter);
$user_count=0;
try {
$cursor = $manager->executeQuery($this->dbName.'.'.$this->userTbl, $prevQuery);
// Iterate over all matched documents
foreach ($cursor as $document) {
$user_count++; //will return 0 if user doesn't exist
}
} catch (MongoDB\Driver\Exception\Exception $e) {
echo $e->getMessage(), "\n";
}
}
}
}
任何建议都将不胜感激。

您忘记将构造函数中创建的1作为类的属性，以便您可以在类中的任何位置使用它

Build For iPhone 5, use armv7s architecture

Note: Unversal libraries you can add into your project and also mention in library search path.
//In order to use the pjsip libraries, we need to include folder that ahve header files that access .a files. Naturally, the header files are located in:
pjlib/include
pjlib-util/include
pjmedia/include
pjnath/include
pjsip/include
Note: do't add into project..buz you can not import like import <pjsip-lib/pjsip.h>
so just place these folder into project directory where ever you want but mention in header search path.
Enjoy (:)
