This article will introduce how to use PHP to implement the live broadcast function on WeChat public accounts, and provide specific code examples to help developers quickly build a live broadcast platform.

1. Preparation

WeChat public account developer account and server, make sure the certification and configuration of the public account have been completed.

$result = file_get_contents($url);
$result = json_decode($result, true);
$access_token = $result['access_token'];
?>

3. Create a live broadcast event

To create a page for a live broadcast event, you can use HTML and CSS to design the interface.

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>创建直播活动</title>
    <style>
        /* 样式表代码 */
    </style>
</head>
<body>
    <h1>创建直播活动</h1>
    <form method="post" action="create_live.php">
        <input type="text" name="title" placeholder="请输入直播标题">
        <input type="submit" value="创建直播">
    </form>
</body>
</html>

PHP code to create a live event.

<?php
$title = $_POST['title'];

// 生成直播活动的唯一标识
$stream_name = uniqid();

// 将直播信息保存到数据库
$conn = mysqli_connect("localhost", "username", "password", "database");
$sql = "INSERT INTO live_streams (stream_name, title) VALUES ('$stream_name', '$title')";
mysqli_query($conn, $sql);

// 调用微信接口创建直播间
$url = "https://api.weixin.qq.com/wxaapi/broadcast/room/create?access_token=$access_token";
$data = array(
    'name' => $title,
    'coverImg' => '直播封面地址',
    'startTime' => '直播开始时间',
    'endTime' => '直播结束时间',
    'anchorName' => '主播名称',
    'anchorWechat' => '主播微信号',
    'anchorImg' => '主播头像地址',
    'shareImg' => '直播分享图片地址'
);
$postData = json_encode($data, JSON_UNESCAPED_UNICODE);
$result = file_get_contents($url, false, stream_context_create(array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-type: application/json',
        'content' => $postData
    )
)));

// 处理微信接口返回的结果
$result = json_decode($result, true);
if ($result['errcode'] == 0) {
    echo "直播创建成功";
} else {
    echo "直播创建失败：" . $result['errmsg'];
}
?>

4. Live broadcast room list and details page

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>直播间列表</title>
    <style>
        /* 样式表代码 */
    </style>
</head>
<body>
    <h1>直播间列表</h1>
    <ul>
        <?php
        $conn = mysqli_connect("localhost", "username", "password", "database");
        $sql = "SELECT * FROM live_streams";
        $result = mysqli_query($conn, $sql);
        while ($row = mysqli_fetch_assoc($result)) {
            echo "<li><a href='stream_detail.php?stream_name=".$row['stream_name']."'>".$row['title']."</a></li>";
        }
        ?>
    </ul>
</body>
</html>

The live broadcast room details page displays the detailed information of the live broadcast and the live broadcast player.

<?php
$stream_name = $_GET['stream_name'];

$conn = mysqli_connect("localhost", "username", "password", "database");
$sql = "SELECT * FROM live_streams WHERE stream_name='$stream_name'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
?>
<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>直播详情</title>
    <style>
        /* 样式表代码 */
    </style>
</head>
<body>
    <h1><?php echo $row['title']; ?></h1>
    <video src="http://livestream.example.com/<?php echo $row['stream_name']; ?>/index.m3u8" autoplay></video>
    <p><?php echo $row['description']; ?></p>
</body>
