PHP实现唤起微信支付功能

本文实例为大家分享了PHP唤起微信支付的具体代码，供大家参考，具体内容如下

'****', //公众账号ID appid 是 String(32) wxd678efh567hg6787 微信分配的公众账号ID（企业号corpid即为此appId）
 'mch_id'=>'****',// 商户号 mch_id 是 String(32) 1230000109 微信支付分配的商户号
 'nonce_str'=>rand(100000,999999),// 随机字符串 nonce_str 是 String(32) 5K8264ILTKCH16CQ2502SI8ZNMTM67VS 随机字符串，不长于32位。推荐随机数生成算法
 'key'=>'****',
 'APPSECRET'=>'*****',
