使用PHP怎么编写一个微信提现功能？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
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;
