默认用法

调用get_currentuserinfo()赋值给$userdata,然后可以通过访问$userdata的成员变量获取这些数据 

<?php global $userdata;
      get_currentuserinfo();

      echo('Username: ' . $userdata->user_login . "\n");
      echo('User level: ' . $userdata->user_level . "\n");
      echo('User ID: ' . $userdata->ID . "\n");
?>
Username: Zedd

User level: 10

User ID: 1

访问全局变量

很多数据被置于独立的全局变量中,可以被直接访问 

<?php global $user_identity , $user_email;
      get_currentuserinfo();

      echo($user_identity . "'s email address is: " . $user_email);
?>
Zedd's email address is: fake@email.com

参数

该函数不接收任何参数,下面程序可用语判断当前是否有用户登录 


<?php global $user_ID;
      get_currentuserinfo();

      if ('' == $user_ID) {
         //no user logged in
      }
