WEB工程師對PHP和JavaScript已經非常瞭解，PHP有一套完整而強大的函數庫，而JavaScript的函數庫則顯得鳳毛麟角，不夠強大。
無意中發現一個開源的js函數庫“php.js"。用JavaScript來實現PHP的函數。涉及數組，對象，時間，加密，文本等非常多的函數。
官方站點爲：http://phpjs.org/
函數代碼：http://kevin.vanzonneveld.net/techblog/category/php2js/
下載地址：http://phpjs.org/packages/download/308/name:php.default.min.js

我們也可以加入開源項目，發佈自己的代碼。
添加新函數：http://phpjs.org/unported/index#unported
改進已有函數：http://phpjs.org/functions/index
