PHP：mysqli插入数据非常慢

Question

我将以下类用于插入数据：

class DB {
  protected static $connection;
    public $num = 0;
    public $insertID = 0;
    public $data = "";
    public $select = "";
    public $error = "";

  public function connect() {
    if(!isset(self::$connection)) {
      self::$connection = mysqli_connect(DB_HOST, DB_USER, DB_PASS, DB_NAME);
      mysqli_query(self::$connection, "SET NAMES 'utf8'");
    }

    if(self::$connection === false) {
      echo 'Not Connect To Database !<br>'.self::$connection->connect_error;
      return false;
    }

    return self::$connection;
  }

  public function query($query) {
    $this->select = $query;
    $q = $this->connect()->query($query);
    $this->connect()->commit();

    return $q;
  }

public function insert($table, $params){
    $before = $after = '';

    foreach($params as $field => $value){
        $before .= "`$field`,";
        $after .= "'$value',";
    }

    $before = substr($before,0,-1);
    $after = substr($after,0,-1);

    $sql = "INSERT INTO `$table` ($before) VALUES ($after)";
    if($this->query($sql)){
        $this->insertID = mysqli_insert_id($this->connect());
    }

    return true;
  }
}

这是我的桌子：

这是我的代码：

$array = array( 'basketPrice'=>$detail['price'],
                    'basketOrder'=>$orderId,
                    'basketGift'=>$userGift,
                    'basketUseCredit'=>$cr,
                    'basketProduct'=>$product,
                    'basketFinish'=>$detail['buyPrice'],
                    'basketExSoon'=>$detail['minus']);

$db = new DB();
$db->insert('basket', $array);

在我的数据库中保存大约80.000条记录。运行代码后，我超时并插入到表中不起作用

basketId，basetGift和basketOrder是索引 为什么？

Answer 1

尝试将记录成束插入。这不会导致超时。尝试将记录拆分为每个呼叫100个插入内容。由于您具有与列关联的索引，因此很明显为什么插入会花费时间。拥有大量索引会影响在DB中插入的性能。因此，明智地选择索引。
