易支付常用php代码

1对数组进行排序[用法sign($data)]

 function paixu($data1){
    ksort($data1);
    $rows = [];
        foreach ($data1 as $key => $value) {
            if (! $value || $key == 'sign') {
                continue;
            }
            $rows[] = "{$key}={$value}";
        }
        $s = implode('&', $rows);
        $s .= $appSecret;

        return $s;
}

header("Location: $url");

3.http_build_query()这个自己百度，返回js跳转代码，地址为变量$url。

$string = http_build_query($data);
      $url = 'http://pay.forwe.co/submit.php?' . $string . '&sign=' . $sign . '&sign_type=MD5';
        $result = "wind（）ow.location.href='".$url."';";

        public function isHTTPS()
    {
        define('HTTPS', false);
        if (defined('HTTPS') && HTTPS) {
            return true;
        }
        if (!isset($_SERVER)) {
            return false;
        }
        if (!isset($_SERVER['HTTPS'])) {
            return false;
        }
        if ($_SERVER['HTTPS'] === 1) {  //Apache
            return true;
        }

        if ($_SERVER['HTTPS'] === 'on') { //IIS
            return true;
        }

        if ($_SERVER['SERVER_PORT'] == 443) { //其他
            return true;
        }
        return false;
    }

5.post提交数据

//post提交函数
function post($url,$data) {
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
   curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
   $output = curl_exec($ch);
   curl_close($ch);
   return $output;
}
