function IDForUsername($id){
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://www.instagram.com/graphql/query/?query_hash=d4d88dc1500312af6f937f7b804c68c3&variables=%7B%22user_id%22%3A%22$id%22%2C%22include_chaining%22%3Atrue%2C%22include_reel%22%3Atrue%2C%22include_suggested_users%22%3Atrue%2C%22include_logged_out_extras%22%3Afalse%2C%22include_highlight_reels%22%3Atrue%2C%22include_live_status%22%3Atrue%7D");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
