iterating through a stdClass object in PHP

Question

I have an object like this:

stdClass Object
(
    [_count] => 10
    [_start] => 0
    [_total] => 37
    [values] => Array
        (
            [0] => stdClass Object

                )

            [2] => stdClass Object

        )

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

Answer 1

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>";

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`
}

Answer 3

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 ){... ...}

Answer 4

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)



        }

Answer 5

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