Question

我得到了

警告：PDO :: prepare（）期望参数2为数组，整数在第29行的/var/www/html/mvc_patern/libs/Model.php中给出

Main Model.php

<?php
  class Model{

public $table;
public $id;
protected $_db;


public function __construct($username = "mvcpatern", $password = "mvcpatern", $host = "localhost", $dbname = "mvcpatern", $options = []){
    // $this->pdo = TRUE;
    try {
        $this->_db = new PDO("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options);
        $this->_db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $this->_db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
    } catch (PDOException $e) {
        throw new Exception($e->getMessage());
    }
}

// get row

public function getRow($id){
    try {
        $stmt = $this->_db->prepare(
        "SELECT *
        FROM `{$this->table}`
        WHERE id={$id})",
        PDO::FETCH_ASSOC);
        $stmt->execute();
        return $stmt->fetch();
    } catch (PDOException $e) {
        throw new Exception($e->getMessage());
    }
}
}
?>

在subModel

中

    <?php
  class Article_Model extends Model {
  public $table = 'articles';
  public $message;
  public function __construct() {
   parent::__construct();
  }    
}
?>

最终调用方法

<?php
      $message = new Article_Model();
      $message->getRow(1);
    ?>

我的方法getRow有什么问题？为什么它要求参数数组，如果我定义了＆＃34; table＆＃34; ＆安培; ＆＃34; ID＆＃34;
