}

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 $hit){     echo $hit; }

thanks

$ytdata->items[0]->snippet->toplevelcomment->snippet->textdisplay not array - it's string.

perhaps meant loop items?

foreach ($ytdata->items $item) {     echo $item->snippet->toplevelcomment->snippet->textdisplay; }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
