所引用的封装类

<?php
class DBDA
{
  public $host = "localhost";
  public $uid = "root";
  public $pwd = "123";
  public $dbname = "test_123";
  //执行SQL语句返回相应的结果
  //$sql 要执行的SQL语句
  //$type 代表SQL语句的类型,0代表增删改,1代表查询
  function query($sql,$type=1)
  {
    $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
    
    $result = $db->query($sql);
    
    if($type)
    {
      //如果是查询,显示数据
      return $result->fetch_all();
    }
    else
    {
      //如果是增删改,返回true或者false
      return $result;
    }
  }
}
