用weiphp生成的自定义菜单如何返回图文消息

上面的地址中的ACCESS_TOKEN是通过凭证接口获取到的凭证。POST参数如下：

{ "button":[ { "type":"click", "name":"今日歌曲", "key":"V1001_TODAY_MUSIC" }, { "type":"click", "name":"歌手简介", "key":"V1001_TODAY_SINGER" }, { "name":"菜单", "sub_button":[ { "type":"click", "name":"hello word", "key":"V1001_HELLO_WORLD" }, { "type":"click", "name":"赞一下我们", "key":"V1001_GOOD" }] }] }

这个POST参数是一个JSON格式的字符串。JSON格式是HTTP网络传送中经常用到的字符串格式。这种格式和PHP的多维数组结合得非常好，JSON格式中中括号包含的字符串对应PHP的数值数组，而大括号内的字符串对应PHP的关联数组。PHP提供了两个内建的函数来处理JSON格式的字符串：json_encode把PHP数组转换成JSON格式的字符串；json_decode把JSON格式的字符串转换成PHP的多维数组。上面的JSON格式的字符串用json_decode函数之后得到的PHP数组如下所示：

array( "button" => array( array( "type" => "click", "name" => "今日歌曲", "key" =>　"V1001_TODAY_MUSIC" ), array( "type" => "click", "name" => "歌手简介", "key" => "V1001_TODAY_SINGER" ), array( "name" => "菜单", "sub_button" => array( array( "type" => "click", "name" => "hello word", "key" => "V1001_HELLO_WORLD" ), array( "type" => "click", "name" => "赞一下我们", "key" => "V1001_GOOD" )
