Google+ Plus API Define a specific image variable - php

Question

I am trying to integrate the Google+ API on my website so that when a user submits approval via Oauth their Google+ activity feed will be displayed.
I have all of it working pretty much and am working on defining the variables that it will display for their feed.
Currently, this is what I have that IS working:
$activityMarkup = '';
foreach($activities['items'] as $activity) {
$url = filter_var($activity['url'], FILTER_VALIDATE_URL);
$title = filter_var($activity['title'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
$content = filter_var($activity['object']['content'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
$published = $activity['published'];
$totalItems = $activity['object']['plusoners']['totalItems'];
$activityMarkup .= "<div class='activity'>
<a href='".$url."' target='_blank'>$title</a>
<div>$content</div>
<div><br/><span>Date Published: </span>$published</div>
<div><br/><span>Total Likes: </span>$totalItems</div>
</div><br/><br>";
What I am trying to get to work is adding in the image that is associated with the post, namely the thumbnail.
I have tried different variations based on using existing code that works, but I just can't figure it out.
According to the Google API, this is the information for that image:
object.attachments[].image object The preview image for photos or videos.
object.attachments[].image.url string URL of the link.
Here's a link to all of the activities available if the above information isn't enough:
https://developers.google.com/+/api/latest/activities#object.originalContent
If someone can help me figure out how to define the variable for the image, that'd be awesome.
I figured it out. If anyone needs it, here's the code.
$image='';
if(isset($activity['object']['attachments'])){
foreach($activity['object']['attachments'] as $att){
if(isset($att['image']['url'])) {
$src = $att['image']['url'];
To call it out:
<img src='$src'>

Answer 1

<?php
$image='';
if(isset($activity['object']['attachments']))
{
foreach($activity['object']['attachments'] as $att)
{
if(isset($att['image']['url']))
{
$src = $att['image']['url'] ;
}
}
}
?>
<img src='<?php echo $src ?>'>

Answer 2

<?php foreach($activities['items'] as $activity): ?>
<div class="activity" >
<div class="title" ><a href="<?php echo($activity['object']['url']) ; ?>" ><?php echo($activity['object']['content']); ?></a></div>
<p>Published at <?php echo($activity['published']); ?></p>
<p>
<?php echo($activity['object']['replies']['totalItems']); ?> Replys .
<?php echo($activity['object']['plusoners']['totalItems']); ?> Plusoners .
<?php echo($activity['object']['resharers']['totalItems']); ?> Reshares
</p>
</div>
<?php endforeach ?>
Another Way to add to the Feed is with replies, plusoners and reshares
