小編給大家分享一下微信支付統一下單用PHP的實現方法，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
H5支付時出現“簽名錯誤”怎么辦？注意調用微信“統一下單”接口后返回pre_pay_id后，需要用戶再次進行簽名返回給HTML； “支付目錄沒有授權”，進入微信商家管理后臺設置即可。
一、Model層，Wxpay.php
<?php
namespace app\common\model;
class Wxpay
{
private $appid = 'wxe8*****d4'; //微信公眾號appid
private $secret = '37c4*******5f0'; //微信公眾號appsecret
private $mchid = '13******02'; //商家號
private $key = '5363e******49e8'; //支付密鑰
private $sslcert_path = 'apiclient_cert.pem'; //證書所在絕對路徑
private $sslkey_path = 'apiclient_key.pem'; //證書所在絕對路徑
public function __construct($appid = '', $secret = '', $mchid = '', $key = '')
{
if(!empty($appid)) $this->appid = $appid;
if(!empty($secret)) $this->secret = $secret;
if(!empty($mchid)) $this->mchid = $mchid;
if(!empty($key)) $this->key= $key;
}

}三、HTML中調用微信支付，wx.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

</html>四、接收微信支付返回結果,支付時設置的notify_url值，確保此鏈接外網能訪問。wxpaynofiy.php
