php结合阿里云（印刷文字识别-身份证识别）进行身份证真实性验证------识别图片中的信息进行验证

1.购买阿里云的套餐：

 

2.查看一下你的AppCode:

3.代码部分：

/**
     * 图片转码
     */
    public function img_base64($path){
        //对path进行判断，如果是本地文件就二进制读取并base64编码，如果是url,则返回
        $img_data="";
        if (substr($path,0,strlen("http")) === "http"){
            $img_data = $path;
        }else{
            if($fp = fopen($path, "rb", 0)) {
                $binary = fread($fp, filesize($path)); // 文件读取
                fclose($fp);
                $img_data = base64_encode($binary); // 转码
            }else{
                return 2;
               // printf("%s 图片不存在",$img_path);
            }
        }
