Iterate though a Object and echo values

Question

I tried a lot of different methods. I managed to get the first part working but the second part to get the fruits name isn't working.

I have an object stored in $food, the print_r() output of this object is shown below:

Food Object
(
    [id] => 1
    [values] => Array
        (
            [name] => Myfood
        )
    [objects] => Array
        (
            [0] => Fruits Object
                (
                    [id] => 1
                    [values] => Array
                        (
                            [name] => My Fruits
                        )
                    [objects] => Array
                        (
                            [0] => FruitType Object
                                (
                                    [id] => 1
                                    [values] => Array
                                        (
                                            [name] => Orange1
                                        )
                                )
                        )
                )
        )
)

This code displays 'Myfood' successfully:

foreach ($food->values as $key => $value) {
    echo "$key => $value";
}

This code displays 'My fruits' successfully:

echo '<br/>';
            
foreach ($food->objects as $id => $owner) {
    foreach ($owner->values as $key => $value) {
        echo "$key => $value";
    }
}
    

I need a second block of code that displays the FruitType object values Orange1, I tried a few things but didn't work out well.

It looks as if you've run into the greatest stumbling block all developers face... naming things. I've probably not done too much better as I'm not 100% sure what your end goal is but you were on the right track as far as nesting loops is concerned.

foreach ($food->objects as $i => $obj) {
    echo "name => {$obj->values['name']}\n";
    foreach ($obj->objects as $j => $type) {
        foreach($type->values as $key => $val){
            echo "    $key => $val\n";
        }
    }
}

Working Example

Looking at the structure of your object though - recursive iteration may be more readable.
