PHP.JS is an open source project in which we try to port PHP functions to JavaScript. By including the PHP.JS library in your own projects, you can use your favorite PHP functions client-side.

Using PHP.JS may speed up development for PHP developers who are increasingly confronted with client-side technology.

It also offers added functionality because JavaScript does not natively support higher-level functions such as: file_get_contents(), mktime(), serialize().

PHP.JS is nothing fancy like jQuery—we're just offering PHP functions, with all of their original flaws and benefits for whomever needs them.
