How do you make someone who has a higher subscriberCount be sorted to the top? For example, I want to list the top 50 by subscriberCount. Currently it just sorts by the order added to $topchan1["items"]. I need to order by the highest subscriberCount.
$topchan1 = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/channels?id='
.$kanalas1.'&part=snippet%2Cstatistics&key='.$API.''),true);
$videoList = array_merge($topchan1["items"],$topchan2["items"],$topchan3["items"],$topchan4["items"]);
foreach ($videoList as $key => $part) {
$sort[$key] = sort($part['statistics']['subscriberCount']);
}
array_multisort($sort, SORT_DESC, $videoList);
$i = 1;
for( $i = 0 ; $i <= count($videoList)-1 ; $i++ )
{
if(isset($videoList[$i]["statistics"]["subscriberCount"])) {
echo $videoList[$i]["statistics"]["subscriberCount"].' _ ';
}
}
how looks

Answer 1

You need to use usort() with custome function where you can compare viewCount and sort array in DESC order
function sortByviewCount($a, $b) {
return ($a['statistics']['viewCount'] > $b['statistics']['viewCount']) ? -1:1;
}
usort($videoList, 'sortByviewCount');
print_r($videoList);
