我的脚本一切正常，但数据没有出现在我的 index.php 中:

数据库.php:
<?php
require ('Users.php');
class Database {
public $db_name = 'authsys_db';
public $host = 'localhost';
public $user = 'root';
public $password = '';
public $con = '';
public $db_handle = '';
public $testMode = TRUE;
public function __construct () {
$this->con = sprintf('mysql:dbname=%s;host=%s', $this->db_name, $this->host);
if ($this->testMode) {
$this->db_handle = new PDO($this->con, $this->user, $this->password,
array(PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING));
} else {
$this->db_handle = new PDO($this->con, $this->user, $this->password);
}
}
public function getUsers ($sql) {
$stmt = $this->db_handle->prepare($sql);
$stmt->execute();
while ($row = $stmt->fetch()) {
$dataSet[] = new Users($row);
}
if (!empty($dataSet))
return $dataSet;
else
return NULL;
}
}
?>
用户.php:
<?php
class Users {
private $id;
private $nom;
private $prenom;
public function __construnct ($row) {
$this->id = $row['ID'];
$this->nom = $row['nom'];
$this->prenom = $row['prenom'];
}
public function getUserId () {
return $this->id;
}
public function getUserNom () {
return $this->nom;
}
public function getUserPrenom () {
return $this->prenom;
}
}
?>
在我的数据库中，用户表中只有一行，我得到了该行，但它是空的，我真的不知道在这里做什么...一点帮助!!
最佳答案
您有一个拼写错误，请将 __construnct 更改为 __construct :
public function __construnct ($row) {
$this->id = $row['ID'];
$this->nom = $row['nom'];
$this->prenom = $row['prenom'];
}
确实，您有一个用户，但由于此拼写错误，他的所有属性都是空的。此外，通过在 __construct() 中设置所有属性来创建用户可能不是最好的方法。
