Strange Youtube Search API behaviour - php

Question

When using the youtube data ip I cannot retrieve a video id. I can use all other fields but get an error accessing the videoId field. The following:
https://www.googleapis.com/youtube/v3/search?key={api_key}&channelId=UCXuqSBlHAE6Xw-yeJA0Tunw&part=snippet,id&order=date&maxResults=2
returns
{

}
Now if I
$videos = json_decode($result)
foreach($videos->items as $video)
{
print_r($video->id->videoId);
}
I get an error
[ErrorException]
Undefined property: stdClass::$videoId
however
print_r($video->id->kind) returns the desired result
also print_r($video->id) returns:
stdClass Object
(
[kind] => youtube#video
[videoId] => dkDq3JJ6IvM
)

Answer 1

It turns out my comment above wasn't the solution.
In actual fact the foreach loop was the issue for some reason:
foreach($videos->items as $video)
{
print_r($video->id->videoId);
}
This didn't work and resulted in the error. Simply replacing $video in the foreach loop with a different word (in this case item) solved it:
foreach($videos->items as $item)
{
print_r($item->id->videoId);
}
