 require 'vendor/autoload.php';
   
use OpenTok\OpenTok;
$apiKey = "key";
$apiSecret = "secret";
$opentok = new OpenTok($apiKey, $apiSecret);
  
use OpenTok\MediaMode;
use OpenTok\ArchiveMode;

// Create a session that attempts to use peer-to-peer streaming:
$session = $opentok->createSession();

// A session that uses the OpenTok Media Router, which is required for archiving:
$session = $opentok->createSession(array( 'mediaMode' => MediaMode::ROUTED ));

// A session with a location hint:
$session = $opentok->createSession(array( 'location' => '12.34.56.78' ));

// An automatically archived session:
$sessionOptions = array(
    'archiveMode' => ArchiveMode::ALWAYS,
    'mediaMode' => MediaMode::ROUTED
);
 $session = $opentok->createSession($sessionOptions);


// Store this sessionId in the database for later use
 $sessionId = $session->getSessionId();
   
   use OpenTok\Session;

// Get stream info from just a sessionId (fetched from a database)
$stream = $opentok->getStream($sessionId, $streamId);

// Stream properties
$stream->id; // string with the stream ID

// Get list of streams from just a sessionId (fetched from a database)
$streamList = $opentok->listStreams($sessionId);

$streamList->totalCount(); // total count 
 
 // Create a simple archive of a session
$archive = $opentok->startArchive($sessionId);


// Create an archive using custom options

    'name' => 'Important Presentation',     // default: null
    'hasAudio' => true,                     // default: true

$archive = $opentok->startArchive($sessionId, $archiveOptions);

// Store this archiveId in the database for later use

// Stop an Archive from an archiveId (fetched from database)

Well, it's just as the error suggests: you're trying to use the variable $streamId, but the interpreter doesn't know this variable, as you didn't create it yet.

I don't know OpenTok, so I'm not sure what it expects here, but you should do something like:

$streamId = 1234

BEFORE using it in $opentok->getStream()

Bro, you're right. I think OpenTok should come and explain this. It's part of the PHP code. Clearly,the has not been defined anywhere as far as I know – Sep 09 '20 at 01:45
