Question

我是php包装类的新手...这里我包含了类文件...我不知道如何编写插入查询... Plz告诉我如何使用下面的编写插入查询类...

class Database {

    public $connection;
    private $host = "localhost";
    private $username = "root";
    private $password = "";
    private $dbname = "property";

    public function __construct() {
        $this->connection = new PDO("mysql:host=$this->host;dbname=$this->dbname", $this->username, $this->password, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
        $this->connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }

    public function insert($query, array $data) {
        $this->connection->prepare($query)->execute($data);
        return $this->connection->lastInsertId();
    }

    public function update($query, array $data) {
        $stmt = $this->executeQuery($query, $data);
        return $stmt->rowCount();
    }

    public function delete($query, array $data) {
        $stmt = $this->executeQuery($query, $data);
        return $stmt->rowCount();
    }

    public function findOne($query, array $data = null) {
        $stmt = $this->executeQuery($query, $data);
        return $stmt->fetchObject();
    }

    public function findMany($query, array $data = null) {
        $stmt = $this->executeQuery($query, $data);
        return($stmt->fetchAll(PDO::FETCH_OBJ));
    }

    public function executeQuery($query, $data = null) {
        $stmt = $this->connection->prepare($query);
        $stmt->execute($data);
        return $stmt;
    }

}

您已经拥有inset()方法，因此请使用

$db = new Database();
$lastId = $db->insert(
    'INSERT INTO `myTable` (`name`, `title`) VALUES (:name, :title)',
    [
        ':name' => 'Name of entry',
        ':title' => 'Title of entry',
    ],
);

var_dump($lastId);

验证数据并将有效数据回显到索引文件
