[YouTube-API] Multiple video edits not working with PHP client library

Hello,

I'm writing some code that loops through videos from a channel and updates them. It works for a channel with 11 videos but for some other channels with 900 or 400 videos, it doesn't do anything. Are there any restrictions on the api that would prevent me from running such code?

I'm using the PHP client library and the code snippet is below:

foreach ($allVideos as $video) {
 printVideoEntry($video);
 $video -> setVideoDescription($descriptionPrefix . " " . $video -> getVideoDescription());
 $youTube -> updateEntry($video, $video -> getEditLink() -> getHref());


 // Verify
 $video = $youTube -> getFullVideoEntry($video -> getVideoId());
 printVideoEntry($video);
 }

Thanks in advance for any help,

George.
