WeChat payment configuration

/*微信支付*/
  'PAY_WEIXIN'        => array(
    'appid'         => 'XXXX',
    'appsecret'       => 'XXXXXXX',
    'mchid'         => '1283301801',                        //商户号
    'key'          => 'zhudianbaodiandodozhudianbao0527',             //商户支付秘钥
    'apiclient_cert'    => 'Conf/cert/apiclient_cert.pem',               //商户证书apiclient_cert.pem
    'apiclient_key'     => 'Conf/cert/apiclient_key.pem',                //商户证书apiclient_key.pem
  )

arrayToXml

/**
* array转xml
*/
function arrayToXml($arr)
{
  $xml = "<xml>";
  foreach ($arr as $key=>$val)
  {
    if (is_numeric($val))
    {
        $xml.="<".$key.">".$val."</".$key.">";
    }
    else
    $xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
  }
  $xml.="</xml>";
  return $xml;
}

Use the certificate to submit xml to the corresponding Interface url

    curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);
    //设置header
    curl_setopt($ch,CURLOPT_HEADER,FALSE);
    //要求结果为字符串且输出到屏幕上
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
