Authenticate Users with a token

To enhance communication security, Agora uses tokens to authenticate users before they access the Agora service, or joining an RTC channel.

Code structure

Under the php directory:

• /src/ contains the source code for generating a token, where RtcTokenBuilder.php is used for generating an RTC token, and RtmTokenBuilder.php is used for generating an RTM token.
• /sample/ contains the sample code for generating a token, where RtcTokenBuilderSample.php is used for generating an RTC token, and RtmTokenBuilderSample.php is used for generating an RTM token.

Generate a token with the sample code

This section takes RtcTokenBuilderSample.cpp as an example to show how to generate a token with the sample code.

Before proceeding, ensure that you have installed the latest version of PHP.

1. Download or clone the Tools repository.

2. Open the DynamicKey/AgoraDynamicKey/php/sample/RtcTokenBuilderSample.php file, replace the value of appID, appCertificate, channelName, and uid with your own, and comment out the code snippets of buildTokenWithUserAccount.

3. Open your Terminal, navigate to the same directory that holds RtcTokenBuilderSample.php, and run the following command. The token is generated and printed in your Terminal window.

   php RtcTokenBuilderSample.php
