I need to get the id and name in an HTML table, but I seem to have a hard time iterating through this object. TIA. I understand that I need to get to the Values Array, and then to the group object, but I trip over the transitions between object and array and foreach vs index based iteration.
我需要在 HTML 表中获取 id 和 name，但我似乎很难遍历这个对象。TIA。我知道我需要访问 Values Array，然后访问 group 对象，但是我在对象和数组之间的转换以及 foreach 与基于索引的迭代之间绊倒了。
For example I tried this:
例如我试过这个：
foreach ($res as $values) { print "\n"; print_r ($values); }
It iterates trough the object, but it also gives me useless
它遍历对象，但它也给了我无用的

echo "<table>"
foreach ($object->values as $arr) {
foreach ($arr as $obj) {
$id = $obj->group->id;
$name = $obj->group->name;
$html = "<tr>";
$html .= "<td>Name : $name</td>";
$html .= "<td>Id : $id</td>";
$html .= "</tr>";
}
}
echo "</table>";

function objectToArray( $data )
{
if ( is_object( $data ) )
$d = get_object_vars( $data );
}
Convert the Object to array first like:
首先将对象转换为数组，如：
$results = objectToArray( $results );
and use
并使用
foreach( $results as result ){... ...}

foreach($res->values as $value) {
print_r($value);
}

I know it's an old post , but for sake of others: when working with stdClass you should use Reflections:
我知道这是一个旧帖子，但为了其他人：使用 stdClass 时，您应该使用Reflections：
$obj = new ReflectionObject($object);
$propeties = $obj->getProperties();
foreach($properties as $property) {
$name = $property->getName(); <-- this is the reflection class
$value = $object->$name; <--- $object is your original $object
here you need to handle the result (store in array etc)
}
