PHP实现微信提现（企业付款到零钱）

怎么开通企业付款到零钱？

有的商户号的产品中心是没有这个功能的，不过，该功能的pid（product id）是5，只要随便进去某一个产品，在地址栏把pid改为5。

即可进入该功能页面，进行开通，不过要满足条件。

用户提现代码：

//用户微信提现
 private function withdrawals_weixin($id){
    $falg = m('withdrawals')->where(['id'=>$id])->find();
    $openid = m('users')->where('user_id', $falg['user_id'])->value('openid');
    $data['openid'] = $openid;
    $data['pay_code'] = $falg['id'].$falg['user_id'];
    $data['desc'] = '提现id'.$falg['id'];
    if($falg['taxfee'] >= $falg['money']){
      return array('status'=>1, 'msg'=>"提现额度必须大于手续费！" );
    }else{
      $data['money'] = bcsub($falg['money'], $falg['taxfee'], 2);
    }
    include_once plugin_path . "payment/weixin/weixin.class.php";
    $weixin_obj = new \weixin();
    $result = $weixin_obj->transfer($data);
   
    return $result;
 }

其中pay_code在商户号的提现功能是唯一的，所以为了防重放攻击，这个值千万不能用随机数，最好用id，具有提现记录唯一。

提现逻辑代码：

// 微信提现转账
  function transfer($data){
    
    header("content-type: text/html; charset=utf-8");
    //ca证书及支付信息
   $wxchat['appid'] = wxpayconfig::$appid;
   $wxchat['mchid'] = wxpayconfig::$mchid;
 
   $wxchat['api_cert'] = plugin_path.'/payment/weixin/cert/apiclient_cert.pem';
    $wxchat['api_key'] = plugin_path.'/payment/weixin/cert/apiclient_key.pem';
    
    // $wxchat['api_ca'] = '/plugins/payment/weixin/cert/rootca.pem';
   $webdata = array(
    'mch_appid' => $wxchat['appid'],
    'mchid'   => $wxchat['mchid'],
    'nonce_str' => md5(time()),
    //'device_info' => '1000',
    'partner_trade_no'=> $data['pay_code'], //商户订单号，需要唯一
    'openid' => $data['openid'],//转账用户的openid
    'check_name'=> 'no_check', //option_check不强制校验真实姓名, force_check：强制 no_check：
    //'re_user_name' => 'jorsh', //收款人用户姓名
    'amount' => $data['money'] * 100, //付款金额单位为分
    'desc'  => $data['desc'],
    'spbill_create_ip' => request()->ip(),
    );
  
   foreach ($webdata as $k => $v) {
   $tarr[] =$k.'='.$v;
    }
 
   sort($tarr);
   $sign = implode($tarr, '&');
   $sign .= '&key='.wxpayconfig::$key;
    $webdata['sign']=strtoupper(md5($sign));
    
    $wget = $this->array2xml($webdata);
    
    $pay_url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers';
 
    $res = $this->http_post($pay_url, $wget, $wxchat);
 
   if(!$res){
   return array('status'=>1, 'msg'=>"can't connect the server" );
   }
    $content = simplexml_load_string($res, 'simplexmlelement', libxml_nocdata);
    
   if(strval($content->return_code) == 'fail'){
   return array('status'=>1, 'msg'=>strval($content->return_msg));
   }
   if(strval($content->result_code) == 'fail'){
   return array('status'=>1, 'msg'=>strval($content->err_code),':'.strval($content->err_code_des));
    }
 
   $rdata = array(
    'mch_appid'    => strval($content->mch_appid),
    'mchid'      => strval($content->mchid),
    'device_info'   => strval($content->device_info),
    'nonce_str'    => strval($content->nonce_str),
    'result_code'   => strval($content->result_code),
    'partner_trade_no' => strval($content->partner_trade_no),
    'payment_no'    => strval($content->payment_no),
    'payment_time'   => strval($content->payment_time),
   );
   return $rdata;
 
  }

其中 plugin_path 是一个常量

define('plugin_path', __dir__ . '/plugins/');

定义插件目录

/**
   * 将一个数组转换为 xml 结构的字符串
   * @param array $arr 要转换的数组
   * @param int $level 节点层级, 1 为 root.
   * @return string xml 结构的字符串
   */
  function array2xml($arr, $level = 1) {
   $s = $level == 1 ? "<xml>" : '';
   foreach($arr as $tagname => $value) {
   if (is_numeric($tagname)) {
    $tagname = $value['tagname'];
    unset($value['tagname']);
   }
   if(!is_array($value)) {
    $s .= "<{$tagname}>".(!is_numeric($value) ? '<![cdata[' : '').$value.(!is_numeric($value) ? ']]>' : '')."</{$tagname}>";
   } else {
    $s .= "<{$tagname}>" . $this->array2xml($value, $level + 1)."</{$tagname}>";
   }
   }
   $s = preg_replace("/([\x01-\x08\x0b-\x0c\x0e-\x1f])+/", ' ', $s);
   return $level == 1 ? $s."</xml>" : $s;
  }
  
  function http_post($url, $param, $wxchat) {
   $ocurl = curl_init();
   if (stripos($url, "https://") !== false) {
   curl_setopt($ocurl, curlopt_ssl_verifypeer, false);
   curl_setopt($ocurl, curlopt_ssl_verifyhost, false);
   }
   if (is_string($param)) {
   $strpost = $param;
   } else {
   $apost = array();
   foreach ($param as $key => $val) {
    $apost[] = $key . "=" . urlencode($val);
   }
   $strpost = join("&", $apost);
   }
   curl_setopt($ocurl, curlopt_url, $url);
   curl_setopt($ocurl, curlopt_returntransfer, 1);
   curl_setopt($ocurl, curlopt_post, true);
   curl_setopt($ocurl, curlopt_postfields, $strpost);

 }
