如何通过呼叫休息呼叫获取CallSid？

I'm using Twilio's rest lib in PHP and making an outgoing call. Can I get the callsid right away i.e.:

$callout = $twilioclient->account->calls->create($client, $phone, $callurl, array("Method"=>"GET"));
$newcallsid=$callout->callsid;

It doesn't seem to be working but, I'm probably doing something wrong.

Thanks in advance for your help.

Change callsid to sid

echo $callout->sid;

You should be able to see all of the properties of the object by echoing it

echo $callout
