php - 数据库更新但仍然抛出异常

Question

我是 PHP OOP 编程新手，当我尝试使用 PHP 更新数据库时，它抛出了这个异常，查询也运行良好，数据库也在更新。但它仍然引发我这个错误

Exception in /var/www/html/thaalinda/includes/querys.inc.php:8 Stack trace: #0 /var/www/html/thaalinda/includes/test.php(12): adminQuery->insertquery(Object(mysqli), 'INSERT INTO ff(...') #1 {main}

这是我的数据库连接代码:

<?php 
class admindatabase{

  protected $host  = "localhost";
  protected $database = "testmy";
  protected $user  = "lkd";
  protected $pwd = "";
  public $connection;

public function connect(){
    $connection = new mysqli($this->host , $this->user , $this->pwd , $this->database);
    if(mysqli_connect_errno()){
        printf("Connect error:%S\n",mysqli_connect_errno());
        exit();
    }
    else{
        return $connection;
    }
}

public function disconnect(ab $connection){
     $connection->close();
    }
}
?>

这是我的查询类

    <?Php
 class adminQuery{

    public function insertquery($con , $query){
       try {
           $con->query($query);

        throw new Exception($con->error);

       } catch (Exception $e) {
        echo $e;
       }
    }
}


 ?>

这是我的测试 PHP

    <?Php
require "./admindatabase.inc.php";
require "./querys.inc.php";


$myob = new admindatabase();

$connection = $myob->connect();

$query = new adminQuery();

$query->insertquery($connection,'INSERT INTO ff(ok) VALUES("Thaalinda BAndara")');
 ?>

Answer 1

    <?Php
 class adminQuery{

    public function insertquery($con , $query){
       try {
           $con->query($query);

           throw new Exception($con->error);  // Here you're throwing the exception manually 

       } catch (Exception $e) {
        echo $e;
       }
    }
}

将其置于 $con->error 时的状态。
