PHP微信支付实例解析_php实例

本文为大家分享了PHP微信支付实例，包括PHP微信支付源码，PHP微信退款源码，php微信支付接口，供大家参考，具体内容如下

1.JSapi支付demo(在微信客户端中点击)

createOauthUrlForCode(WxPayConf_pub::JS_API_CALL_URL);
 Header("Location: $url"); 
 }else
 {
 //获取code码，以获取openid
  $code = $_GET['code'];
 $jsApi->setCode($code);
 $openid = $jsApi->getOpenId();
 }
 
 //=========步骤2：使用统一支付接口，获取prepay_id============
 //使用统一支付接口
 $unifiedOrder = new UnifiedOrder_pub();
 
 //设置统一支付接口参数
 //设置必填参数
 //appid已填,商户无需重复填写
 //mch_id已填,商户无需重复填写
 //noncestr已填,商户无需重复填写
 //spbill_create_ip已填,商户无需重复填写
 //sign已填,商户无需重复填写
