How PHP connects with Tencent Cloud audio and video communication services to realize real-time audio and video call functions

With the rapid development of the Internet, real-time audio and video calls have become one of the important ways for people to communicate. Tencent Cloud Real-Time Communication (TRTC) provides a series of powerful APIs to facilitate developers to quickly implement real-time audio and video call functions. This article will introduce how to use PHP to connect to Tencent Cloud audio and video communication services, and give code examples.

Step 1: Create a Tencent Cloud account and activate audio and video services

First, we need to create an account on the official Tencent Cloud website and activate audio and video communication services. The specific steps are as follows:

1. Visit the official Tencent Cloud website (link: https://cloud.tencent.com/).
2. Register a Tencent Cloud account and log in.
3. Select [Audio and Video Service]-[Cloud Live Broadcast]-[Application Management] in the console, create an application and obtain the SDKAppID and key information.

Step 2: Download TRTC SDK

To connect the TRTC service in the PHP project, we need to use the TRTC SDK file. TRTC SDK can be downloaded from the official Tencent Cloud website. After the download is complete, unzip the file and copy the relevant files to the project directory.

Step 3: Write PHP code to connect to TRTC

The following is a simple PHP code example that implements the function of real-time audio and video calls through the TRTC service. The code uses the API provided by Tencent Cloud TRTC SDK. Specific functions include initializing TRTC instances, joining rooms, turning on cameras and microphones, sending video and audio data, etc.

<?php
require_once 'trtcapi.php';

// 初始化 TRTC 实例
$trtc = new trtcapi();

// 设置 SDKAppID 和密钥信息
$trtc->setConfig([
    'sdkAppId' => 'YOUR_SDK_APP_ID',
    'secretKey' => 'YOUR_SECRET_KEY',
]);

// 加入房间
$room = $trtc->joinRoom([
    'userID' => 'USER_ID',
    'roomID' => 'ROOM_ID',
    'userSig' => 'USER_SIG',
]);

// 打开摄像头和麦克风
$trtc->startLocalPreview([
    'canvas' => ['view' => 'local_video_view'],
]);
$trtc->startLocalAudio();

// 发送视频和音频数据
while (true) {
    $videoFrame = // 获取视频帧数据
    $audioFrame = // 获取音频帧数据
    
    $trtc->sendVideoFrame($videoFrame);
    $trtc->sendAudioFrame($audioFrame);
}

// 退出房间
$trtc->exitRoom([
    'roomID' => 'ROOM_ID',
]);

// 销毁 TRTC 实例
$trtc->destroy();

?>

In the specific code implementation, parameters need to be configured and processed according to your own business needs. For example, YOUR_SDK_APP_ID and YOUR_SECRET_KEY need to be replaced with the actual values ​​obtained when creating the application in the Tencent Cloud account. USER_ID, ROOM_ID and USER_SIG also need to be set according to the actual situation.

It should be noted that TRTC SDK provides a rich API interface to meet the development of different scenarios and needs. Developers can make corresponding calls and extensions according to their own needs. For example, you can add listeners for audio and video calls to handle events and callbacks during the call.

Summary:

This article introduces how to use PHP to connect to Tencent Cloud Audio and Video Communication Service (TRTC), and gives a simple code example. Through TRTC services, developers can quickly implement real-time audio and video call functions to provide a better communication and communication experience. I hope this article can be helpful to your development work. For more detailed information about TRTC, please visit the official Tencent Cloud website.
