How to iterate through a nested stdClass? [duplicate]

Question

I have an object like this:

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.

For example I tried this:

foreach ($res as $values) { print "\n"; print_r ($values); }

It iterates trough the object, but it also gives me useless

Will you show what you tried and explain how your attempt did not match your expectations? — George Cummins

Thanks @adeneo, This got me further: foreach ($res->values as $values) { print "\n"; foreach ($values->group as $groups) { but I get stuck here. $groups is not an array. If I try to access it by index I get 5C 2D 1S 3C 4B 3I 5I 6S 4I 4M ... — Mordechai

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>";

There you go, I was just guessing the structure of a table there, but if you got it working, that's the important part.

Since this is the top result in Google if you search for iterate over stdclass it may be helpful to answer the question in the title:

You can iterate overa stdclass simply by using foreach:

$user = new \stdClass();
$user->flag = 'red';

foreach ($user as $key => $value) {
   // $key is `flag`
   // $value is `red`
}

function objectToArray( $data ) 
{
    if ( is_object( $data ) ) 
        $d = get_object_vars( $data );
}

Convert the Object to array first like:

$results = objectToArray( $results );

and use

foreach( $results as result ){... ...}

Where is the return statement?

I know it's an old post , but for sake of others: when working with stdClass you should use 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)



        }

Worked like a charm for me. Take not that this sample uses an interpolated object property name $object->$name, which is set in the line above.

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