}

MY PHP CODE

$json = file_get_contents('https://www.googleapis.com/youtube/v3/commentThreads?part=snippet%2Creplies&videoId='.$videoid.'&key='.$apikey);
$ytdata = json_decode($json);
foreach($ytdata->items[0]->snippet->topLevelComment->snippet->textDisplay as $hit){
    echo $hit;
}

Thanks

$ytdata->items[0]->snippet->topLevelComment->snippet->textDisplay is not an array - it's a string.

Perhaps you meant to loop the items?

foreach ($ytdata->items as $item) {
    echo $item->snippet->topLevelComment->snippet->textDisplay;
}
