php支付系列

網路上的許多PHP支付寶支付接入教學都頗為複雜，且需要配置和引入較多的文件，本人透過整理後給出一個單文件版的，希望可以給各位想接入支付寶支付的帶來些許幫助和借鏡意義。本文我們就和大家分享一個PHP檔案搞定支付寶系列之電腦網站支付教學知識，希望能幫助大家。

環境依賴

PHP5.0以上，且需要開啟CURL服務、SSL服務。

注意事項

1.檔案開頭的設定資訊必須完善
2.商家私鑰需填寫對應簽章演算法類型的私鑰，如何產生金鑰參考：
2.1 https://docs.open.alipay.com/...
2.2 https://docs.open.alipay.com/...
