How to use PHP to develop the menu management function of public accounts

With the popularity of WeChat public accounts, many companies choose to use public accounts for publicity and promotion. The menu management function of public accounts is very important for improving user experience and increasing interactivity. In this article, I will introduce how to use PHP to develop the menu management function of the official account and provide specific code examples.

1. Preparation work
   First, we need to obtain the developer account of the WeChat public platform and activate the interface permissions. After opening the interface permission, we will obtain a unique AppId and AppSecret. These two pieces of information are credentials for communicating with the WeChat public platform, and we need to keep them in a safe place.
2. Get access_token
   When communicating with the WeChat public platform, we need to provide an access_token to verify the legality of the current operation. We can obtain the access_token by calling the interface provided by the WeChat public platform. The following is a code example to obtain access_token:

$appid = 'your_app_id'; // 替换为你的AppId
$appsecret = 'your_app_secret'; // 替换为你的AppSecret

$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

$result = json_decode($output, true);
$access_token = $result['access_token'];

3. Create Menu
   After obtaining the access_token, we can use it to create a menu. The following is a code example for creating a menu:

$menu = array(
    'button' => array(
        array(
            'type' => 'click',
            'name' => '菜单1',
            'key' => 'menu1',
        ),
        array(
            'type' => 'view',
            'name' => '菜单2',
            'url' => 'http://www.example.com/menu2',
        ),
        array(
            'name' => '菜单3',
            'sub_button' => array(
                array(
                    'type' => 'click',
                    'name' => '子菜单1',
                    'key' => 'sub_menu1',
                ),
                array(
                    'type' => 'view',
                    'name' => '子菜单2',
                    'url' => 'http://www.example.com/sub_menu2',
                ),
            ),
        ),
    ),
);

$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=$access_token";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($menu, JSON_UNESCAPED_UNICODE));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

$result = json_decode($output, true);
if ($result['errcode'] == 0) {
    echo '菜单创建成功！';
} else {
    echo '菜单创建失败：' . $result['errmsg'];
}

The above code example defines a menu array containing multiple menu items. The menu array is converted into JSON by calling the interface provided by the WeChat public platform. format and send it to the WeChat public platform. If the menu is created successfully, the errcode field in the returned result will be 0, otherwise it will be an error message.

Summary:
This article introduces how to use PHP to develop the menu management function of public accounts and provides specific code examples. By obtaining the access_token and using it to create the menu, we can easily manage the menu of the official account and provide a better user experience. Hope this article is helpful to you!
