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

//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。
