PHP中怎么实现微信提现功能，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
封装提现的方法
function tixian($money){ $appid = "################";//商户账号appid $secret = "##########";//api密码 $mch_id = "#######";//商户号 $mch_no = "#######"; $openid="123456789";//授权用户openid $arr = array(); $arr['mch_appid'] = $appid; $arr['mchid'] = $mch_id; $arr['nonce_str'] = ugv::randomid(20);//随机字符串，不长于32位 $arr['partner_trade_no'] = '1298016501' . date("Ymd") . rand(10000, 90000) . rand(10000, 90000);//商户订单号 $arr['openid'] = $openid; $arr['check_name'] = 'NO_CHECK';//是否验证用户真实姓名，这里不验证 $arr['amount'] = $money;//付款金额，单位为分 $desc = "###提现"; $arr['desc'] = $desc;//描述信息 $arr['spbill_create_ip'] = '192.168.0.1';//获取服务器的ip //封装的关于签名的算法 $notify = new Notify_pub(); $notify->weixin_app_config = array(); $notify->weixin_app_config['KEY'] = $mch_no; $arr['sign'] = $notify->getSign($arr);//签名 $var = $notify->arrayToXml($arr); $xml = $this->curl_post_ssl('https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers', $var, 30, array(), 1); $rdata = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA); $return_code = (string)$rdata->return_code; $result_code = (string)$rdata->result_code; $return_code = trim(strtoupper($return_code)); $result_code = trim(strtoupper($result_code)); if ($return_code == 'SUCCESS' && $result_code == 'SUCCESS') { $isrr = array( 'con'=>'ok', 'error' => 0, ); } else { $returnmsg = (string)$rdata->return_msg; $isrr = array( 'error' => 1, 'errmsg' => $returnmsg, ); } return json_encode($isrr); }用到的curl_post_ssl()
function curl_post_ssl($url, $vars, $second = 30, $aHeader = array()) { $isdir = "/cert/";//证书位置 $ch = curl_init();//初始化curl curl_setopt($ch, CURLOPT_TIMEOUT, $second);//设置执行最长秒数 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上 curl_setopt($ch, CURLOPT_URL, $url);//抓取指定网页 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);// 终止从服务端进行验证 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);// curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM');//证书类型 curl_setopt($ch, CURLOPT_SSLCERT, $isdir . 'apiclient_cert.pem');//证书位置 curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');//CURLOPT_SSLKEY中规定的私钥的加密类型 curl_setopt($ch, CURLOPT_SSLKEY, $isdir . 'apiclient_key.pem');//证书位置 curl_setopt($ch, CURLOPT_CAINFO, 'PEM'); curl_setopt($ch, CURLOPT_CAINFO, $isdir . 'rootca.pem'); if (count($aHeader) >= 1) { curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);//设置头部 } curl_setopt($ch, CURLOPT_POST, 1);//post提交方式 curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);//全部数据使用HTTP协议中的"POST"操作来发送 $data = curl_exec($ch);//执行回话 if ($data) { curl_close($ch); return $data; } else { $error = curl_errno($ch); echo "call faild, errorCode:$error\n"; curl_close($ch); return false; } }关于具体签名算法，可参考微信官方文档；
简单示范签名算法：
//将要发送的数据整理为$data ksort($data);//排序 //使用URL键值对的格式（即key1=value1&key2=value2…）拼接成字符串 $str=''; foreach($data as $k=>$v) { $str.=$k.'='.$v.'&'; } //拼接API密钥 $str.='key='.$secrect; $data['sign']=md5($str);//加密将数组转换成xml格式（简单方法）：
//遍历数组方法 function arraytoxml($data){ $str='<xml>'; foreach($data as $k=>$v) { $str.='<'.$k.'>'.$v.'</'.$k.'>'; } $str.='</xml>'; return $str; }将xml格式转换为数组：
function xmltoarray($xml) { //禁止引用外部xml实体 libxml_disable_entity_loader(true); $xmlstring = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA); $val = json_decode(json_encode($xmlstring),true); return $val; }下面来看看ThinkPHP5封装的提现类。
