这是我的代码:

include 'conn.php';
$conn = new Connection();
$query = 'SELECT EmailVerified, Blocked FROM users WHERE Email = ? AND SLA = ? AND `Password` = ?';
$stmt = $conn->mysqli->prepare($query);
$stmt->bind_param('sss', $_POST['EmailID'], $_POST['SLA'], $_POST['Password']);
$stmt->execute();
$result = $stmt->get_result();

我在最后一行得到错误:调用未定义的方法mysqli_stmt :: get_result()

这是conn.php的代码:

define('SERVER', 'localhost');
define('USER', 'root');
define('PASS', 'xxxx');
define('DB', 'xxxx');
class Connection{
    /**
     * @var Resource 
     */
    var $mysqli = null;

    function __construct(){
        try{
            if(!$this->mysqli){
                $this->mysqli = new MySQLi(SERVER, USER, PASS, DB);
                if(!$this->mysqli)
                    throw new Exception('Could not create connection using …

我有一个SQL查询和一个mysqli预处理语句:

$sql = 'SELECT photographers.photographer_id, photographers.photographer_name
    FROM photographers';

$stmt = $conn->stmt_init(); 
if ($stmt->prepare($sql)) { 
    $stmt->bind_result($photographer_id, $photographer_name);  
    $OK = $stmt->execute(); 
    $stmt->fetch();
}

如何将结果存储在关联数组中,以便稍后循环并获取sql字符串返回的所有数据？
