打印 stdClass 对象 [英] Printing an stdClass object

问题描述

我有:

$value = $wpdb->get_row("SELECT custom_message FROM `wp_wpsc_cart_contents` WHERE purchaseid='" . $purchase_log['id'] . "'");

如果我这样做:

print_r($value);

我明白了:

stdClass Object
(
    [custom_message] =>  |Castor Seed Oil  $4.45| 
)

所以我试图获得那个价值:

So I tried to get that value doing:

foreach($value as $index => $result) {
   echo $result["custom_message"];
}

我也试过:

foreach($value as $index => $result) {
   echo $result->custom_message;
}

但是没有打印任何东西，知道我在这里做错了什么吗?

but that prints nothing, any idea what I'm doing wrong here?

推荐答案

循环什么都不做，你正在迭代一个具有单个属性的对象，你已经知道它的名称.只需这样做:

The loop does nothing, you are iterating an object with a single property that you already know the name of. Just do this:

echo $value->custom_message;
