php版微信实现公众号菜单添加删除操作

为了以最快方式调试新菜单功能，就用Debug方式去生成新菜单。请参数微信教程2的 wechat-json类。导入该文件后，我们用Debug方式生成一个新菜单：
if (isset($argc)  && $argc >= 1 && $argv[0] == __FILE__) {
    $client = new WechatJSON(array(
        WechatJSON::APP_ID => 'wx78acfe8023sfsd4d51',
        WechatJSON::APP_SECRET => '9ba3476db1ffsfsf512e0b22f630fa',
    ));
 
    $res = $client->call('/menu/create',array (
            'button' => array(
                array (
                    'name' => '扫码',
                    'sub_button' => array(
                        array(
                            'name' => '扫码不提示',
                            'type' => 'scancode_push',
                            'key' => 'rselfmenu_0_0',
                            'sub_button' =>array ()
                        ),
                        array(
                            'name' => '扫码带提示',
                            'type' => 'scancode_waitmsg',
                            'key' => 'rselfmenu_0_1',
                            'sub_button' =>array ()
                        ),
                    ),
                ),
                array(
                    'name' => '发图',
                    'sub_button' => array(
                        array(
                            'name' => '系统拍照发图',
                            'type' => 'pic_sysphoto',
                            'key' => 'rselfmenu_1_0',
                            'sub_button' => array()
                        ),
                        array(
                            'name' => '拍照或者相册发图',
                            'type' => 'pic_photo_or_album',
                            'key' => 'rselfmenu_1_1',
                            'sub_button' => array()
                        ),
                        array(
                            'name' => '微信相册发图',
                            'type' => 'pic_weixin',
                            'key' => 'rselfmenu_1_2',
                            'sub_button' => array()
                        ),
                    )
                ),
                array(
                    'name' => '发送位置',
                    'type' => 'location_select',
                    'key' => 'rselfmenu_2_0'
                )
            )
        )
        , WechatJSON::JSON);
    if (!$res) {
        var_dump($client->_error);
    }
    var_export($res);
}

执行后，取消关注再关注，让新菜单生效！
效果图：

测试结果如下：
scancode_push事件:
array (
  'tousername' => 'gh_e2a2b3bd35ff',
  'fromusername' => 'on0eVjnYStxkCSaaCamYCpMZDmwA',
  'createtime' => '1411629272',
  'msgtype' => 'event',
  'event' => 'scancode_push',
  'eventkey' => '6',
  'scancodeinfo' =>
  SimpleXMLElement::__set_state(array(
     'ScanType' => 'qrcode',
     'ScanResult' => 'http://www.baidu.com/',
  )),
array (
  'tousername' => 'gh_e2a2b3bd35ff',
  'fromusername' => 'on0eVjnYStxkCSaaCamYCpMZDmwA',
  'createtime' => '1411629475',
  'msgtype' => 'event',
  'event' => 'scancode_push',
  'eventkey' => '6',
  'scancodeinfo' =>
  SimpleXMLElement::__set_state(array(
     'ScanType' => 'qrcode/EAN_13',
     'ScanResult' => '6925082946487',
     'EventKey' =>
    SimpleXMLElement::__set_state(array(
    )),
  )),
)

上面是在菜单上点击《扫码不提示》后的log，有两种情况出现，第一种是如果你扫的是二维码是URL，它就会跳转到网页（注包括服务号生成的二维码），第二种是如果你扫的是条形码，就会跳转到搜索到该商品的详细信息，也就是大家常用的查价格。

scancode_waitmsg事件：
array (
  'tousername' => 'gh_e2a2b3bd35ff',
  'fromusername' => 'on0eVjnYStxkCSaaCamYCpMZDmwA',
  'createtime' => '1411629302',
  'msgtype' => 'event',
  'event' => 'scancode_waitmsg',
  'eventkey' => '6',
  'scancodeinfo' =>
  SimpleXMLElement::__set_state(array(
     'ScanType' => 'qrcode',
     'ScanResult' => 'http://www.111com.net/',
  )),

上面是点击菜单《扫码提示》后的log，推送XML跟scancode_push时差不多,但它不会跳转到网址或者商品信息。博主认为，这有利于后台取得scancodeinfo的信息来进一步处理！打个比方，自己自定义二维码信息，然后截取处理。类似于原服务号的参数二维码。
注意，以上两个菜单扫描事件和微信APP的扫一扫，是有区别的。具体你看事件就能看出来，scan事件！
pic_sysphoto事件、pic_photo_or_album事件和pic_weixin事件
array (
  'tousername' => 'gh_e2a2b3bd35ff',
  'fromusername' => 'on0eVjnYStxkCSaaCamYCpMZDmwA',
  'createtime' => '1411627313',
  'msgtype' => 'image',
  'picurl' => 'http://mmbiz.qpic.cn/mmbiz/L8zbjcLqNFvEZ4dne4MGQQGR8xuHk4KhEk3icghU6a4bFTXnP2oeicr5VaBVJa10w4MYOOEia4udqicT5fdtAADHYg/0',
  'msgid' => '6062893143676022221',
  'mediaid' => 'i7hYOlSXbUCaC7Z9Elx4WpBqQq37-hR0El5w-frPfD5WCdBC7x46DPO6HL7zMfgd',
)

上面是点《发图》后，三个子菜单选择或者拍好，发图后的log信息，从图中我们看到事件是推过来了image，其他信息，相信大家都知道是什么，不解释。
location_select事件：
array (
  'tousername' => 'gh_e2a2b3bd35ff',
  'fromusername' => 'on0eVjnYStxkCSaaCamYCpMZDmwA',
  'createtime' => '1411627424',
  'msgtype' => 'event',
  'event' => 'location_select',
  'eventkey' => '6',
  'sendlocationinfo' =>
  SimpleXMLElement::__set_state(array(
     'Location_X' => '23',
     'Location_Y' => '113',
     'Scale' => '15',
     'Label' =>
    SimpleXMLElement::__set_state(array(
    )),
     'Poiname' =>
    SimpleXMLElement::__set_state(array(
    )),
  )),
)

上面是点击菜单《发送位置》后的log，我们可以看出事件是location_select，不像发图那样变成image,最有价值的信息是我们要取的sendlocationinfo里的
