PHP mysqli_kill() 函数

返回当前连接的线程 ID，然后杀死连接：

   <?php
   $con=mysqli_connect("localhost","my_user","my_password","my_db");
   // 检测连接
   if (mysqli_connect_errno($con))
   {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
   }
  
  // 获取线程 ID
  $t_id=mysqli_thread_id($con);
  
  // 杀死线程
  mysqli_kill($con,$t_id);
  ?>
