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 wi感动中国观后感结尾thdrawals_weixin($id){    $falg = m('withdrawals')->where(['id'=>$id])->find();    $openid = m('urs')->where('ur_id', $falg['ur_id'])->value('openid');    $data['openid'] = $openid;    $data['pay_code'] = $fal中国传媒大学本科招生网g['id'].$falg['ur_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！" );    }el{      $data['money'] = bcsub($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; chart=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_ur_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);   $sign辣警霸王花 电影 = implode($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 rver" );   }    $content = simplexml_load_string($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($content->nonce雅思口语part2_str),    'result_code'   => strval($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 = $value['tagname'];    unt($value['tagname']);   }   if(!is_array($value)) {    $s .= "<{$tagname}>".(!is_numeric($value) ? '<![cdata[' : '').$value.(!is_numeric($value) ? ']]>' : '')."</{$tagname}>";   } el {    $s .= "<{$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://") !== fal) {   curl_topt($ocurl, curlopt_ssl_verifypeer, fal);   curl_topt($ocurl, curlopt_ssl_verifyhost, fal);   }   if (is_string($param)) {   $strpost = $param;   } el {   $apost = array();   foreach ($param as $key => $val) {    $apost[] = $key . "=" . urlencode($val);   }   $strpost = join("&", $apost);   }   curl_topt($ocurl, curlopt_url, $url);   curl_topt($ocurl, curlopt_returntransfer, 1);   curl_topt($ocurl, curlopt_post, true);   curl_topt($o自由的工作curl, curlopt_postfields, $strpost);   if($wxchat){   curl_topt($ocurl,curlopt_sslcert,$wxchat['api_cert']);   curl_topt($ocurl,curlopt_sslkey,$wxchat['api_key']);   curl_topt($ocurl,curlopt_cainfo,$wxchat['api_ca']);   }   $scontent = curl_exec($ocurl);   $astatus = curl_getinfo($ocurl);    curl_clo($ocurl);       if (intval($astatus["http_code"]) == 200) {   return $scontent;   } el {   return fal;   } }
