How can i print all the ['message'] ? I tried:
foreach ($graphObject as $key => $value) {
echo '<br>'.$key['message'];
}
But i got a error. Thank you for your help.

Your array has some keys which elements are actually StdClass. You can't reffer to it as $key['message'] but as: $key->message.
Also, don't forget to include your error message. An error is extremely generic and we can't/won't help you if there is no indication of what is wrong.
I didn't notice your foreach. As you are iterating only on $graphObject first level, you will get as $key data and as value another whole array which each key has a StdClass. On your foreach, run it as foreach ($graphObject['data'] as $key => $value) , then use it as echo $value->message
