分享一个PHP微信端开发的经验，有时候当一个项目或工程需要微信端分享之后做一系列事件那么我们就需要获取到微信分享这个动作，也就是说我们已经知道了当前这个东西已经被分享了 ，那么走微信默认的分享显然是不行的我们需要自己动手来配置微信分享，当用户分享时走的是我们预定好的程序那么我们就可以轻松实现分享之后所做的事情。
在页面端主要是一个js如下：
<div class="jb51code">
<pre class="brush:js;">
<script type="text/javascript" src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js">
rush:
PHP;">
appId = $appId;
$this->appSecret = $appSecret;
}
public function getSignPackage() {
$jsapiTicket = $this->getJsApiTicket();
// 注意 URL 一定要动态
获取，不能 hardcode.
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
$url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$timestamp = time();
$nonceStr = $this->createNonce
str();
// 这里参数的顺序要按照 key 值 ASCII 码升序排序
$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
$signature = sha1($string);
$signPackage = array(
"appId" => $this->appId,"nonceStr" => $nonceStr,"timestamp" => $timestamp,"url" => $url,"signature" => $signature,"rawString" => $string
);

for ($i = 0; $i < $length; $i++) {
$str .= substr($chars,mt_rand(0,strlen($chars) - 1),1);
}

}
