## 1. 引入 icomet.js ##

##    2. 引入相关的详细配置 ##

## 3. 编写服务端的 注册接口 和 发送消息接口 ##

### (1) 注册接口 ###

//这里用 cookie 或者 session 或者  memcache 存储当前用户cname
    $cb = urlencode($_GET['cb']);
    $cname = urlencode($_GET['cname']);
    
    $_COOKIE['cname'] = $cname
    
    $url = "http://127.0.0.1:8000/sign?cname=$cname&cb=$cb";
    $resp = http_get($url);
    echo $resp;
    
    function http_get($url){
    	$ch = curl_init($url) ;
    	curl_setopt($ch, CURLOPT_HEADER, 0);
    	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1) ;
    	$result = curl_exec($ch) ;
    	curl_close($ch) ;
    	return $result;
    }

###       (2) 消息推送接口 ###

if(get_magic_quotes_gpc()){
    	$_GET['content'] = stripslashes($_GET['content']);
    }
    $cname = trim($_GET['cname']);
    $content = trim($_GET['content']);
    
    if($_COOKIE['cname'] == $cname){
        //检验当前登陆是否是本人
    }
    
    echo icomet_push($cname, $content);
    
    function icomet_push($cname, $content){
    	$cname = urlencode($cname);
    	$content = urlencode($content);
    	$url = "http://127.0.0.1:8000/push?cname=$cname&content=$content";
    
    	$ch = curl_init($url) ;
    	curl_setopt($ch, CURLOPT_HEADER, 0);
    	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1) ;
    	$result = @curl_exec($ch) ;
    	curl_close($ch) ;
    	return $result;
    }
