微信群发图文，content中图片显示不出

}

}

$data = urldecode(json_encode($data));

做了双引号->单引号的转义,发送的data数据包如上，发送后content中的文字能显示图片不能显示,希望大家能给我一点思路，哪里还有问题，谢谢

htmlspecialchars_decode($data['article'] ['content'], ENT_QUOTES);

content里面的图片也需要上传到微信服务才能显示出来，可以用正则匹配出来图片，上传一下换取微信的地址。
具体的可以参照下边这个方法

public function upload_weixin_img($content, $res_id)
    {
        $img = array();
        preg_match_all('\']*?>\'', $content, $img);

        // 如果没有图片信息 直接返回原内容
        if (!isset($img[0]) || !$img[0]) {
            return $content;
        }

        // 如果存在图片，取出图片内容，进行上传
        $pattern ='';

        foreach ($img[0] as $k=>$v) {
            $html = $v;
            preg_match($pattern, $html, $matches);

            if ($matches[1]) {
                //在关联表创建对应关系
                $filter = array(
                    'res_id'    => $res_id,
                    'old_src'   => $matches[1]
                );
                $info = _model('material_img_relation')->read($filter);
                if ($info) {
                    $content = str_replace($matches[1], $info['new_src'], $content);
                } else {
                    $matche_str = $matches[1];
                    // 进行图片路径替换
                    $str = str_replace(SITE_URL.'/static/upload', '', $matches[1]);
                    $str = UPLOAD_PATH.$str;

                    // 上传图片
                    $url = 'https://api.weixin.qq.com/cgi-bin/media/uploadimg?access_token='.$this->access_token;

                    $result = an_curl($url, $data, true);

                    // 替换文件路径,改变原内容
                    if (isset($result['errcode']) && $result['errcode'] == 40001) {
                        $this->check_app_params();
                        $url = 'https://api.weixin.qq.com/cgi-bin/media/uploadimg?access_token='.$this->access_token;
                        $data = array(

                        $result = an_curl($url, $data, true);
                    }

                    $new_src = $result['url'];

                    $data = array(
                        'res_id'    => $res_id,
