How to loop through objects in php

Question

I am not too familiar with objects, i usually convert them to arrays using a script, but i thought it was time to man up and learn this, so i am asking how can i loop through an array of objects and pull out the specific information i need, the example of what is being returned is below.

[2] => stdClass Object
        (
            [id_str] => 152240682071900161
            [in_reply_to_status_id] => 
            [contributors] => 
            [place] => 
            [truncated] => 
            [geo] => 
            [favorited] =>

How about showing us the code you've tried? What exactly is "the specific information [you] need?" — Matt Ball

you dont need to convert them to anything.

foreach loop would work fine with you as follows in generic:

foreach ($objects as $obj) {
   echo $obj->property;
}

for a inner object this would work:

foreach ($objects as $obj){
      echo $obj->user->description;
}

Actually is the opposite: foreach ($objects as $obj)
