PHP實現站點pv，uv統計（一）

具體步驟分爲數據採集腳本，數據收取服務，數據分析腳本，數據存儲服務

採集腳本通常有兩種形式，一種是簡單的頁面插入一個圖片進行請求，一種是複雜的動態生成js標籤，引入一段js(這時採集服務器會網往客戶端寫cookie)，js採集瀏覽器數據與cookie，而後發送請求。

數據收取服務通常爲web服務，能夠是apache，nginx，或者swoole，這裏主要看採集的壓力，適當作負載均衡，能夠愛腳本端作，也能夠在服務端作，注意客戶端ip的穿透。

腳本分析可使用任何腳本，例如php，python。

數據存儲分爲兩部，一個是採集數據的存儲，一個是分析以後的數據的存儲，通常來說原始數據是需呀保留的，因此原始數據採集可使用文本保存在單機，或者使用redis等可固話的存儲容器保存。

　　選用不一樣的形式對擴展之後的服務有必定的影響，暫且不談，在pv/uv只有幾百萬的站點，或者幾千萬的站點web服務壓力基本不大，天天的原始數據存儲會有幾百M。

　　細節上可使用不一樣的技術，例如加入memcached緩存，使用多進程多線程等

 

我使用的方案是使用nginx作採集web服務器，使用js腳本採集數據，採集的數據按五分鐘分500個文件存儲避免文本的衝突，而後php五分鐘按期處理數據，統計結果記入redis保存。

 

js採集腳本以下：

        dm: [
            {$dm}

腳本的函數說明以下：

//定義p方法，將傳入的參數轉換爲字符串形式

//定義q方法，從字符串a裏找出含有字符串b的值，若是沒有則爲null，貌似是從url請求參數裏獲取值

//定義v方法，取url中協議後的第一個/以前的內容並將端口號去掉，例如http://www.18touch.com:999/ 過濾以後獲得www.18touch.com

 //定義w方法，在html5的屬性sessionStorage裏存放window.sessionStorage[a]=b;,百度統計存放的是訪問時間，估計用於計算回話時間

//定義x方法，在html5的屬性sessionStorage裏取出w方法定義的key爲a的值，不支持這個屬性返回null

 //定義y方法，設置cookie，a=b,cookie的屬性在d對象裏面

//定義z方法,請求a地址，並作記錄，在請求完成，出錯，拒絕以後，重置。若是定義了回調b方法，則執行b（a);

//定義D方法，全局變量A爲空則執行將A變成一個userdata對象，用於ie瀏覽器儲存數據，報錯返回false；全局變量A不爲空返回true；

 //定義E方法，若是支持window.localStorage，則保持window.localStorage[a]=now+d|b,若是不支持再看是否支持userdata，若是支持，在域名下使用userdata存儲a=b,過時時間爲now+d

//定義H方法，若是沒有過時的話取出從E方法存儲的key爲a的值，不然返回null。

//定義I方法，在a元素上綁定事件b，處理函數爲d

//定義N方法，判讀a的類型是否爲b

//定義V方法，啓動統計功能

//定義V原型方法，

//定義pa方法，從sessionStorage裏取Hm_unsent_字符串，按,分隔，依次調用z方法發送請求，並調用回調函數X

//定義X方法，用做請求後的回調，去掉sessionStorage裏的Hm_unsent_字符串裏的請求url，若是Hm_unsent_爲空，刪除Hm_unsent_

//定義qa方法，在sessionStorage裏的key：Hm_unsent_後添加url b，若是a.a.u存在，後面還要添加&u=當前url的後綴

//定義W方法，調用qa往sessionStorage的Hm_unsent_裏存儲url：hm.baidu.com/hm.gif，調用z方法發送請求，並執行回調X

//定義sa方法，返回一個初始化a.a數組，並執行觸發請求的方法，在window.beforeunload觸發，關閉頁面時觸發

//定義ka方法，執行信息收集與消息發送，以及事件監聽

 //定義ra方法，組裝R請求的字符串，數據從a.a數組裏面獲取

//定義na方法，從cookie，sessionStorage，localStorage，usedata刪除Hm_cv_

//定義ma方法，若是當前href在以域名配置數組裏的開頭，返回/以及以後的部分

 //定義la方法，取當前域名，若是域名數組裏有當前域名結尾的，返回域名數組裏的配置項，不然返回當前域名

 //定義Y方法，判斷url a的域是否在域數組裏

 //定義wa方法，判斷字符串b是不是url a的開頭

//定義Z方法，判斷去除端口號以後的url b，是不是 url a的結尾部分

//定義ta方法，綁定window的focusin，focusout事件，須要瀏覽器支持a.j爲加載後的時間

//定義$方法，檢測window的focus與blur事件，計算a.d爲最後操做時間，a.i爲操做累計時間
