分享一个完整的微信开发php代码

这篇文章主要为大家分享一个完整的微信开发php代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了微信开发php代码，供大家参考，具体内容如下<?php//封装成一个微信接口类class WeixinApi{private $appid;private $appsecret;//构造方法 初始化赋值public function construct($appid="",$appsecret=""){$this->appid = $appid;$this->appsecret = $appsecret;}//验证服务器地址有效性public function valid(){if($this->checkSignature()){$echostr = $_GET['echostr'];//随机的字符串return $echostr;}else{return "Error";}}//检查签名private function checkSignature(){//一、接收微信服务器GET方式提交过来的4个参数数据$signature = $_GET['signature'];//微信加密签名$timestamp = $_GET['timestamp'];//时间戳$nonce = $_GET['nonce'];//随机数//二、加密/校验过程// 1. 将token、timestamp、nonce三个参数进行字典序排序；// bool sort ( array &$array [, int $sort_flags = SORT_REGULAR ] ) 对数组排序$tmpArr = array(TOKEN,$timestamp,$nonce);//将上面三个参数放到一个数组里面sort($tmpArr,SORT_STRING);// 2. 将三个参数字符串拼接成一个字符串进行sha1加密；$tmpStr = implode($tmpArr); //将数组转化成字符串$signatureStr = sha1($tmpStr);// 3. 开发者获得加密后的字符串与signature对比。if($signatureStr == $signature){return true;}else{return false;}}//响应消息public function responseMsg(){//接收微信服务器发送POST请求到开发者服务器，携带的XML数据包$postData = $GLOBALS['HTTP_RAW_POST_DATA'];//处理xml数据包$xmlObj =
