Question

我有这个函数返回一个数组对象

static public function GetFeaturedArticle($db) {

    try {

        $statement = $db->prepare("SELECT a.*, u.username FROM articles a LEFT JOIN users u ON a.user_id = u.id WHERE a.featured = TRUE LIMIT 1");
        $statement->execute();      

        while ($record = $statement->fetch(PDO::FETCH_ASSOC)) {
            // i have to process some data here and i want to return 
            // associative array back
            $obj = new self($db);
            $obj->processInput($record);
            $obj->processPhotoField();

        }

    } catch (PDOException $ex) {
        if (HOST_TYPE ==="dev") {
            echo "<pre>"; print_r($ex); echo "</pre>";
        }
        throw ($ex);
    }
    // the return type i'm not sure of
    return get_object_vars($obj);       
}

我试图访问我的属性

<?php echo $this->featured_article->data["id"]; ?>

但是我得到一个致命的错误：注意：尝试在第27行的C：\ wamp \ www \ winepress \ www \ templates \ home.tpl.php中获取非对象的属性

这是我的var转储

如何访问我的数据属性并回显我的数据

<?php echo $this->featured_article->data["id"]; ?>

Answer 1

您尝试使用

访问类属性

featured_article->data

但根据您的var_dump输出，您有一个数组。

所以你必须用

访问它

featured_article['data']

所以你的行应该是

<?php echo $this->featured_article['data']['id']; ?>

访问没有按预期工作的accossiated数组值
