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, $strPOST);
 if($wxchat){
 curl_setopt($oCurl,CURLOPT_SSLCERT,$wxchat['api_cert']);
 curl_setopt($oCurl,CURLOPT_SSLKEY,$wxchat['api_key']);
 curl_setopt($oCurl,CURLOPT_CAINFO,$wxchat['api_ca']);
 }
 $sContent = curl_exec($oCurl);
 $aStatus = curl_getinfo($oCurl);
 curl_close($oCurl);

 if (intval($aStatus["http_code"]) == 200) {
