angularJS socket，angularjssocket

項目Controller檔案中載入Service層socket.js.頁面進入該controller所在頁面時串連socket(也可一進入項目就串連，看需求)，細節還需繼續最佳化，寫下來以防忘了~

php的運行環境

給你推薦一個軟體Xampp。
就像安裝windows一樣，安裝之後，不需要怎麼配置，你的電腦就成為了一台PHP+MySQL+FTP的伺服器了。比較傻瓜，上網搜一下就好了。
 
PHP的網站難不那，需要什方面的知識

我倒是覺得PHP不錯。
你需要先看看html是怎麼回事？
然後知道C的過程。
然後你就自然而然知道了PHP!
