了解一下如何使用PHP实现微信分享功能

<script src="http://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>

$timestamp = time();
$nonceStr = 'your_noncestr';
$url = 'http://yourdomain.com/yourpage.php';
$jsTicket = getJsTicket(); //获取微信JS-SDK的ticket

$signature = sha1("jsapi_ticket=$jsTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url");
//注意要按照字典序排序

$config = array(
    'appId' => 'your_appid',
    'timestamp' => $timestamp,
    'nonceStr' => $nonceStr,
    'signature' => $signature
);

wx.onMenuShareTimeline({
    title: '分享标题',
    link: '分享链接',
    imgUrl: '分享图标',
    success: function () {
        //分享成功后执行的回调函数
    },
    cancel: function () {
        //取消分享后执行的回调函数
    }
});

wx.onMenuShareAppMessage({
    title: '分享标题',
    desc: '分享描述',
    link: '分享链接',
    imgUrl: '分享图标',
    type: '分享类型',
    dataUrl: '分享数据',
    success: function () {
        //分享成功后执行的回调函数
    },
    cancel: function () {
        //取消分享后执行的回调函数
    }
});
