php与阿里云短信接口接入

使用阿里云短信API，需要在控制台获取以下必要参数，其中需要自己手机验证+官方审核多次，尤其审核需要保持耐心。

1. accessKeyId 相当于你的个人账户密钥；

2. accessKeySecret 与上是成对的；

3. SignName 个人签名，在发出去的短信中，这个签名会显示在开头，类似【签名】亲爱的用户...... 这种格式，SignName需要通过提交审核；

4.TemplateCode 模板代码，阿里云短信是无法完全自定义短信的，需要通过审核的模板，然后自己再替换掉模板中的变量，如模板：“您的验证码是${code}” ,code就是变量，使用时需设置变量值{"code"："12345"}(设置变量值的过程在demo中实现)，短信发出去后变成：“您的验证码是12345”，每个通过审核的模板会提供一个模板代码；

最新的阿里云短信接口，适用于阿里大于搬家以后的情况。
之前一直用阿里大于的短信接口，最近上项目时发现阿里大于悄悄地搬家到了阿里云！阿里云的SDK文件繁多，看得一头雾水！下面代码是最新的可适用于阿里云短信服务的类，亲测成功！

}

调用方法：

//生成验证码
$mobile = \'xxxxxxx\';
$code = rand ( 1000, 9999 );
//发送短信
$sms = new Sms();

//测试模式
$status = $sms->send_verify($mobile, $code);
if (!$status) {
  echo $sms->error;

}
