php order that nested loops run in - php

Question

I have a piece of code that retrieves data from the Facebook api. Basically what happens is I loop over all the posts in our own database. For each posts it will try to get all shares for that post from the Facebook api. The Facebook api retrieves an object with a next link for the next batch of shares for that posts and it will keep looping till it gets all shares and go on to the next post.
The code looks as follows (Note that this is not my actual code because it has way to many things going on that are not important or needed for my question):
// SELECT all posts from my database
$sql = "SELECT * FROM posts";
$result = $con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
try {
//this is our api call to get all share posts
$response = $fb-get($row['postId'] . "someApiEndPointForSharedPosts");
//start processing the response for the post
processFeed($response);
} catch (Exception $e) {
//There is no response or there is another error
echo 'Caught exception: ', $e->getMessage(), "\n";
}
}
}
function processFeed($shares){
//Go through all shares in the response and do some modification and storage etc
foreach($shares as $share){
//Do something with the share
}
//Facebook sdk method to get the next batch of shares for the post (if there are any left)
$nextFeed = fb->next($shares);
//If there are more shares run this function again with the new batch
if(isset($nextFeed)){
processFeed($nextFeed);
}
}
Now my question is. Will the code run in the following order:
Select all post
Do the api call for the first post (which returns an response)
Start process feed with the response for the first post
Check if there is a next feed for the first post
If there is run process feed agian till there is no next feed left for the first post
Start over by doing the api call for the second post and do the above process agian.
