In the WeChat public account, through well-designed marketing activities, you can effectively attract user attention, enhance brand exposure, increase user interaction, and promote sales growth.

This article will be based on PHP, describing how to use PHP to implement marketing activities for WeChat public accounts, and provide specific code examples for reference.

1. Get the user's attention events
   In the WeChat public account, the user's attention to the public account is a prerequisite for carrying out activities, so it is necessary to determine whether the user has followed the public account.

The sample code is as follows:

// 接收微信服务器发送的数据
$postStr = file_get_contents("php://input");
if (!empty($postStr)) {
    // 解析XML数据
    $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
    $fromUser = $postObj->FromUserName; // 用户openid
    $toUser = $postObj->ToUserName; // 公众号原始ID
    
    if ($postObj->MsgType == 'event' && $postObj->Event == 'subscribe') {
        // 用户关注事件处理逻辑
        // 可以进行关注后的欢迎语发送、赠送优惠券等操作
    }
}

2. Automatic reply message
   When the user sends a message to the official account, you can set an automatic reply to answer the user's questions or promote activities wait.

The sample code is as follows:

// 判断是否为文本消息类型
if ($postObj->MsgType == 'text') {
    $content = trim($postObj->Content); // 获取用户发送的文本消息内容
    // 根据不同的关键词做出不同的回复
    if ($content == '活动') {
        $replyMsg = "我们正在开展一项限时活动，购买即可享受优惠，详情请查看我们的公众号文章。";
    } elseif ($content == '客服') {
        $replyMsg = "您可以通过以下方式联系我们的客服：电话：XXXXX，邮箱：XXXXX。";
    } else {
        $replyMsg = "感谢您的留言，我们会尽快给您回复。";
    }
    
    // 组装回复消息XML
    $resultXml = "<xml>
                    <ToUserName><![CDATA[" . $fromUser . "]]></ToUserName>
                    <FromUserName><![CDATA[" . $toUser . "]]></FromUserName>
                    <CreateTime>" . time() . "</CreateTime>
                    <MsgType><![CDATA[text]]></MsgType>
                    <Content><![CDATA[" . $replyMsg . "]]></Content>
                  </xml>";
    echo $resultXml;
}

3. Menu function
   In the public account menu, you can set some commonly used function buttons to facilitate users to quickly obtain information or participate in activities .

The sample code is as follows:

// 创建菜单
function create_menu($menuData) {
    $accessToken = get_access_token();
    $url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" . $accessToken;
    $result = http_post($url, $menuData);
    $resultArr = json_decode($result, true);
    if ($resultArr["errmsg"] == "ok") {
        return true;
    } else {
        return false;
    }
}

// 删除菜单
function delete_menu() {
    $accessToken = get_access_token();
    $url = "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=" . $accessToken;
    $result = http_get($url);
    $resultArr = json_decode($result, true);
    if ($resultArr["errcode"] == 0) {
        return true;
    } else {
        return false;
    }
}

// 菜单数据示例
$menuData = '{
    "button": [
        {
            "name": "最新活动",
            "sub_button": [
                {
                    "type": "view",
                    "name": "活动一",
                    "url": "https://www.example.com/activity1"
                },
                {
                    "type": "view",
                    "name": "活动二",
                    "url": "https://www.example.com/activity2"
                }
            ]
        },
        {
            "name": "客服",
            "type": "click",
            "key": "contact_service"
        }
    ]
}';

// 创建菜单
create_menu($menuData);

// 删除菜单
delete_menu();
