我是靠谱客的博主感动镜子，最近开发中收集的这篇文章主要介绍php实现微信公众号企业转账功能，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

企业付款提供由商户直接付钱至用户微信零钱的能力，支持平台操作及接口调用两种方式，资金到账速度快，使用及查询方便。主要用来解决合理的商户对用户付款需求，比如：保险理赔、彩票兑换等等。

特点

发起方式灵活，可通过页面或接口发起
微信消息触达，用户及时获知入账详情
支持实名校验，判断收款人真实身份
通过openid即可实现付款，无需用户敏感隐私信息
到账速度快，在发起后，用户可在几分钟内收到付款

企业转账需要到微信商户平台=》产品中心=》企业付款到零钱，开启此功能

下面是程序截图：

第一步：设置配置参数

$url='https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers';
$pars = array();
$pars['mch_appid'] =$this->module['config']['appid'];
$pars['mchid']=$this->module['config']['mchid'];
$pars['nonce_str'] =random(32);
$pars['partner_trade_no'] =time().random(3,1);
$pars['openid'] =$openid;
$pars['check_name'] ='NO_CHECK' ;
//$pars['re_user_name'] ='' ;
$monet_finall = $price * 100;
$pars['amount'] =$monet_finall; //这里是折算成1%的所以要*100
$pars['desc'] ='您已成功提现 '.$price.' 现金';
$pars['spbill_create_ip'] =$this->module['config']['ip'];

ksort($pars, SORT_STRING);
$string1 = '';
foreach ($pars as $k => $v) {
  $string1 .= "{$k}={$v}&";
}

$string1 .= "key=".$this->module['config']['password'];
$pars['sign'] = strtoupper(md5($string1));
$xml = array2xml($pars);
$extras = array();
$extras['CURLOPT_CAINFO'] = ATTACHMENT_ROOT . '/withdraw/cert/rootca.pem.' . $_W['uniacid'];
$extras['CURLOPT_SSLCERT'] = ATTACHMENT_ROOT   . '/withdraw/cert/apiclient_cert.pem.' . $_W['uniacid'];
$extras['CURLOPT_SSLKEY'] = ATTACHMENT_ROOT . '/withdraw/cert/apiclient_key.pem.' . $_W['uniacid'];
$procResult = null;

第二步：CURL请求微信服务器

load()->func('communication');
$resp = ihttp_request($url, $xml, $extras);

其中ihttp_request函数内容是：

function ihttp_request($url, $post = '', $extra = array(), $timeout = 60) {
  $urlset = parse_url($url);
  if (empty($urlset['path'])) {
   $urlset['path'] = '/';
  }
  if (!empty($urlset['query'])) {
   $urlset['query'] = "?{$urlset['query']}";
  }
  if (empty($urlset['port'])) {
     }
  if (strexists($url, 'https://') && !extension_loaded('openssl')) {
   if (!extension_loaded("openssl")) {
     message('请开启您PHP环境的openssl');
   }
  }
  if (function_exists('curl_init') && function_exists('curl_exec')) {
   $ch = curl_init();
   if (!empty($extra['ip'])) {
     $extra['Host'] = $urlset['host'];
     $urlset['host'] = $extra['ip'];
     unset($extra['ip']);
   }
   curl_setopt($ch, CURLOPT_URL, $urlset['scheme'] . '://' . $urlset['host'] . ($urlset['port'] == '80' || empty($urlset['port']) ? '' : ':' . $urlset['port']) . $urlset['path'] . $urlset['query']);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
   curl_setopt($ch, CURLOPT_HEADER, 1);
   @curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
   if ($post) {
     if (is_array($post)) {
      $filepost = false;
            foreach ($post as $name => &$value) {
        if (version_compare(phpversion(), '5.6') >= 0 && substr($value, 0, 1) == '@') {
         $value = new CURLFile(ltrim($value, '@'));
        }
        if ((is_string($value) && substr($value, 0, 1) == '@') || (class_exists('CURLFile') && $value instanceof CURLFile)) {
         $filepost = true;
        }
      }
      if (!$filepost) {
        $post = http_build_query($post);
      }
     }
     curl_setopt($ch, CURLOPT_POST, 1);
     curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
   }
   if (!empty($GLOBALS['_W']['config']['setting']['proxy'])) {
     $urls = parse_url($GLOBALS['_W']['config']['setting']['proxy']['host']);
     if (!empty($urls['host'])) {
      curl_setopt($ch, CURLOPT_PROXY, "{$urls['host']}:{$urls['port']}");
      $proxytype = 'CURLPROXY_' . strtoupper($urls['scheme']);
      if (!empty($urls['scheme']) && defined($proxytype)) {
        curl_setopt($ch, CURLOPT_PROXYTYPE, constant($proxytype));
      } else {
        curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
        curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
      }
      if (!empty($GLOBALS['_W']['config']['setting']['proxy']['auth'])) {
        curl_setopt($ch, CURLOPT_PROXYUSERPWD, $GLOBALS['_W']['config']['setting']['proxy']['auth']);
      }
     }
   }
   curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
   curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
   curl_setopt($ch, CURLOPT_SSLVERSION, 1);
   if (defined('CURL_SSLVERSION_TLSv1')) {
     curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
   }
   curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1');
   if (!empty($extra) && is_array($extra)) {
     $headers = array();
     foreach ($extra as $opt => $value) {
      if (strexists($opt, 'CURLOPT_')) {
        curl_setopt($ch, constant($opt), $value);
      } elseif (is_numeric($opt)) {
        curl_setopt($ch, $opt, $value);
      } else {
        $headers[] = "{$opt}: {$value}";
      }
     }
     if (!empty($headers)) {
      curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
     }
   }
   $data = curl_exec($ch);
   $status = curl_getinfo($ch);
   $errno = curl_errno($ch);
   $error = curl_error($ch);
   curl_close($ch);
   if ($errno || empty($data)) {
     return error(1, $error);
   } else {
     return ihttp_response_parse($data);
   }
  }
  $method = empty($post) ? 'GET' : 'POST';
  $fdata = "{$method} {$urlset['path']}{$urlset['query']} HTTP/1.1rn";
  $fdata .= "Host: {$urlset['host']}rn";
  if (function_exists('gzdecode')) {
   $fdata .= "Accept-Encoding: gzip, deflatern";
  }
  $fdata .= "Connection: closern";
  if (!empty($extra) && is_array($extra)) {
   foreach ($extra as $opt => $value) {
     if (!strexists($opt, 'CURLOPT_')) {
      $fdata .= "{$opt}: {$value}rn";
     }
   }
  }
  $body = '';
  if ($post) {
   if (is_array($post)) {
     $body = http_build_query($post);
   } else {
     $body = urlencode($post);
   }
   $fdata .= 'Content-Length: ' . strlen($body) . "rnrn{$body}";
  } else {
   $fdata .= "rn";
  }
  if ($urlset['scheme'] == 'https') {
   $fp = fsockopen('ssl://' . $urlset['host'], $urlset['port'], $errno, $error);
  } else {
   $fp = fsockopen($urlset['host'], $urlset['port'], $errno, $error);
  }
  stream_set_blocking($fp, true);
  stream_set_timeout($fp, $timeout);
  if (!$fp) {
   return error(1, $error);
  } else {
   fwrite($fp, $fdata);
   $content = '';
   while (!feof($fp))
     $content .= fgets($fp, 512);
   fclose($fp);
   return ihttp_response_parse($content, true);
  }
}

第三步：解析分析微信服务器返回值并返回。

if (is_error($resp)) {
  $procResult = $resp;
} else {
  $arr=json_decode(json_encode((array) simplexml_load_string($resp['content'])), true);
  $xml = '<?xml version="1.0" encoding="utf-8"?>' . $resp['content'];
  $dom = new DOMDocument();
  if ($dom->loadXML($xml)) {
    $xpath = new DOMXPath($dom);
    $code = $xpath->evaluate('string(//xml/return_code)');
    $ret = $xpath->evaluate('string(//xml/result_code)');
    if (strtolower($code) == 'success' && strtolower($ret) == 'success') {
      $procResult = array('errno'=>0,'error'=>'success');;
    } else {
      $error = $xpath->evaluate('string(//xml/err_code_des)');
      $procResult = array('errno'=>-2,'error'=>$error);
    }
  } else {
    $procResult = array('errno'=>-1,'error'=>'未知错误');
  }
}

return $procResult;
