PHP实现APNS推送

参考http://code.google.com/p/apns-php/作为修改 上面的项目实现很完全，其中包括了队列。服务端实现等，但是功能过于复杂。简单的使用觉得不顺手！ 用了几个小时，参考其过程，写了一个class文件，直接使用即可。简单且好理解 闲话少说，上代码 ?php/*** @

使用办法：

include 'apns.php';
$rootpath = 'entrust_root_certification_authority.pem';  //ROOT证书地址
$cp = 'production_push_certificates.pem';  //provider证书地址
$apns = new APNS(0,$cp);
try
{
    $apns->setRCA($rootpath);  //设置ROOT证书
    $apns->connect(); //连接
    $apns->addDT('b9d98721b5586b61a00fbfa0d61a033954e1bfb8faaae3dfc5a1382xxxxxx');  //加入deviceToken
    $apns->setText('这是一条测试信息');  //发送内容
    $apns->setBadge(1);  //设置图标数
    $apns->setSound();  //设置声音
    $apns->setExpiry(3600);  //过期时间
    $apns->setCP('fljt',array('type' => '1','url' => 'http://www.google.com.hk'));  //自定义操作
    $apns->send();  //发送
}catch(Exception $e)
{
    echo $e;
