Connection Token Creation — PHP

In order to authenticate a user connecting to an OpenTok session, a client must connect using a token (see this overview).

The following PHP code example shows how to generate a token using the OpenTok PHP server-side library:

<?PHP

use OpenTok\OpenTok;

$opentok = new OpenTok(API_KEY,API_SECRET);
// Replace with the correct session ID:
print $opentok->generateToken('your_session_ID');
print "\n";
?>

Calling the generateToken() method returns a string. This string is the token. Use server-side PHP code to include the token in the served web page.

The following PHP code example shows how to obtain a token that has a role of "publisher" and that has a connection metadata string:

<?PHP

use OpenTok\OpenTok;

$opentok = new OpenTok(API_KEY,API_SECRET);
// Replace with meaningful metadata for the connection:
$connectionMetaData = "username=Bob,userLevel=4"; 
// Replace with the correct session ID:
print $opentok->generateToken('your_session_ID', array('role' => RoleConstants::PUBLISHER, 'expireTime' => time()+(7 * 24 * 60 * 60), 'data' =>  $connectionMetaData); 
print "\n";
?>

The method takes the following arguments:
