构建一个Wordpress插件

Question

我正在制作一个wordpress插件，并且我使用查询从数据库获取所需的所有数据，但之后我无法弄清楚如何解析它。

我的查询是：

$dbContent = $wpdb->get_results("SELECT option_id, option_name, option_value FROM wp_options WHERE option_name LIKE '%Customizer%'"); 

，我展示它使用：

$retval .= "<pre>"; 
     $retval .= print_r($dbContent); 
     $retval .= "</pre>"; 

我得到这个，我认为是一个数组的数组：

Array ([0] => stdClass Object ([option_id] => 119587 [option_name] => bfhCustomizer_price_1 [option_value] => 2.85) [1] => stdClass Object ([option_id] => 119584 [option_name] => bfhCustomizer_option1 [option_value] => Leave-In Moisturizer) [2] => stdClass Object ([option_id] => 119585 [option_name] => bfhCustomizer_option2 [option_value] => Conditioner/Cleansing Conditioner) [3] => stdClass Object ([option_id] => 119586 [option_name] => bfhCustomizer_option3 [option_value] => Pure Oil Mixture) [4] => stdClass Object ([option_id] => 119588 [option_name] => bfhCustomizer_price_2 [option_value] => 3.45) [5] => stdClass Object ([option_id] => 119589 [option_name] => bfhCustomizer_price_3 [option_value] => 1.99) [6] => stdClass Object ([option_id] => etc... 

莫非

有人告诉我如何正确访问这个？我试图用类似$dbContent->option_id或$dbContent['option_id']但既不工作，我在这里失去了现在

看起来你有stdClass的对象的数组，这样你就可以像这样访问：

$id = $dbContent[0]->option_id; 

// or in a loop 

foreach($dbContent as $index => $result) { 
    echo $result->option_id; 
    echo $result->option_name; 
    // etc 
}
